Subject: build: Fix detection of valac

AM_PROG_VALAC very helpfully sets $VALAC to:
"Absolute path to the Vala compiler, or simply ‘valac’ if no suitable
compiler Vala could be found at configure runtime."

We were checking for $VALAC being empty, thus still trying to build Vala
plugins even if Vala wasn't available.
