Subject: [PATCH] luau-compile: Fix usage of vector-ctor without vector-lib

When --vector-lib is not specified, CompileOptions::vectorLib was set to an empty string.
This resulted in the builtin matching not working, since vectorLib must either be a null
pointer or a pointer to a valid global identifier.
