On a clean install, `configure` checks that the installation prefix exists, is owned by the mailman group, has the setgid bit set, and has permissions >= 02775. But `make install` never created or configured the prefix directory itself — only its subdirectories — causing a chicken-and-egg failure.

Add `MAILMAN_GROUP= @MAILMAN_GROUP@` to `Makefile.in` and have `doinstall` create the prefix, `chgrp` it to the mailman group, and `chmod` it 02775 before creating any subdirectories.

iconv -o is a GNU iconv extension not supported on BSD. Replace the
subprocess call with Python's own open() encoding support, which is
portable and removes the iconv dependency entirely.
Replace file -bi encoding detection with a Python-native UTF-8 open
attempt. If the file opens cleanly as UTF-8, skip it; otherwise
convert from the known locale encoding. No external tools needed.
Detects legacy SHA1 hex digest passwords that need upgrading to
the PBKDF2 format introduced by hash_password().
sha_new() requires bytes in Python 3 but was receiving a str.
Switch to hash_password() so new lists get PBKDF2 hashes from
the start rather than legacy SHA1. Fixes jaredmauch#24.
'Hit enter to notify %(listname)s owner...' was never interpolated.
Replace print()+readline() with input() which handles both the prompt
and waiting for Enter in one call.
check_perms and Mailman/MTA/Postfix.py both had Python 2-style
print C_('...') % locals(), statements where the migration to Python 3
dropped the % locals() substitution, leaving literal %(varname)s in
error output. Also fix two bare print -> print() in Postfix.py.
BSD make does not have a wildcard function -- it treats the argument
as a variable name with spaces, generating warnings. Use $(POFILES)
in messages/ (already defined) and drop the dependency list in
templates/ (stamp file is sufficient for a clean build).
distutils was removed in Python 3.12. The configure check was using
distutils.sysconfig solely to verify Python development headers exist.
Replace with the sysconfig stdlib module (available since Python 3.2)
using sysconfig.get_path('include') in place of get_python_inc().
configure checks that the installation prefix exists, is owned by the
mailman group, has the setgid bit, and has permissions >= 02775. But
make install never created or configured the prefix directory itself,
causing a chicken-and-egg failure on clean installs.

Add MAILMAN_GROUP= @MAILMAN_GROUP@ to Makefile.in and have doinstall
create the prefix, chgrp it to the mailman group, and chmod it 02775
before creating any subdirectories.
