media-tv/mythtv: upstream bump and bug fixes

Bump to latest upstream 0.27-fixes branch. Add a MYTHBACKEND_LOGGING option
to allow users to specify custom logging options instead of always having
/var/log/mythtv hardcoded on them. (bug #493396 & bug #442996). Prevent
installing scripts that need the Perl bindings when USE=-perl is set.
Similiarly prevent Python script installation when USE=-python is set.
(bug #516968). Add missing dependency on udisks:0 when USE=dvd or
USE=bluray is set. (bug #456898 & bug #503806). Drop 'need net' in the
init script in favor of 'use net.lo'. (bug #439656). Add lame as a
dependency always, reported and fixed by Olav Sandstå
<olav@sandstaa.net>). (bug #440006).
