- updated pl.po-update patch
- forcedotlock patch is back, now fixing only sgid install
- pass mutt_cv_{group,world}write to stabilize builds not to depend on local
  /var/mail permissions and get proper sgid support
- don't pass --with-homespool as it disables --with-mailpath and sgid support;
  maildir support is still available through $MAILDIR envvar

Changed files:
    mutt.spec -> 1.199
