autofs-5.0.7 - Allow nsswitch.conf to not contain "automount:" lines

From: Michael Tokarev <mjt@tls.msk.ru>

Current code does not allow a case when nsswitch.conf

does not mention automount map at all, like all new

installations.  It logs a rather unpleasant error

message instead:

 syntax error in nsswitch config near [ syntax error ]

this patch has a minimal fix, to allo "file" to be empty.

Whole parser in C is about 25 lines of code, the "grammar"

is trivial, and it is better to ditch all this yacc/lex

stuff, but that will be much more intrusive change.
