autofs-5.0.7 - dont fail on master map self include

From: Ian Kent <raven@themaw.net>

When reading the master map a self included file map should skip the source
and proceed to the next so, in this case, return an nss status that will
allow the map read to continue. In particular not NSS_STATUS_UNAVAIL which
causes the lookup to record a failure or NSS_STATUS_SUCCESS which indicates
a successful lookup and termintes the reading of sources.
