[meson] Run check-symbols.sh and check-static-inits.sh correctly

* Search src/ build directory for objects in check-static-inits.sh
* Find .def files in src/ build directory in src/check-symbols.sh
* Pass builddir also in autotools also, we may just remove libs passing after autotools removal
* Move harfbuzz_subset_def target so can be referenced as a check-static-inits.sh dependency
