Subject: [PATCH] Add support for config setting to enable/disable UTMP-related
 files creation during boot.

musl libc does not natively support UTMP and so some musl-basd distros
may not make use of/update UTMP files (i.e. Alpine in the scenario where
the utmps package in not installed or configured).

Other Linux distros, especially those using systemd, may be making use
of wtmpdb (via systemd-login) as an alternative.

Therefore it makes sense to provide a configuration setting to prevent
OpenRC from creating utmp-related files.
