community/autofs: upgrade to 5.19 and take maintainership

Updated patches. Some were no longer necessary, some needed refresh. Also added one patch from gentoo and one from void.

Adjust the build configuration:

    the --with-confdir switch was pointing to the openrc conf.d, but what is expected is where automount will find the autofs.conf file
    added --enable-force-shutdown switch (possibly temporary, needs more testing)
    changed --sysconfigdir switch to the system sysconfdir, now that the --with-confdir is set as expected
    stop removing the autofs(5) manpage
    added etc/autofs/auto.master.d directory, which is referenced in the etc/autofs/auto.master file

Get logging working for automount: Because the initd script is using the supervise-daemon supervisor and starting automount with the -f (foreground) switch, all logging from automount is lost to stderr. Add supervise-daemon stderr logfile to remedy the situation.
