maint.mk: fix syntax checks without exclusions
Commit 727075d0 skipped per-line exclusions if ${exclude} is left
undefined, but was immediately broken by commit 44de969c which
always initialized the variable to the empty string.
* top/maint.mk (_sc_search_regexp): Allow for empty variable.
Reported by Daniel P. Berrange.
