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.
