vala: don't build .h, .vala, and .gir if export_dynamic is False

dcbaker · nirbheek · commit a92e2b1ba3ad · 2023-02-19T03:04:06.000+05:30
The current check results in *any* value to `export_dynamic` generating
vala import targets, even `false`. This is pretty clearly wrong, as it
really wants to treat an unset export_dynamic as false.
