chore(build): Remove '-pie' linker flag and fix strmiids dependency on Windows

One part fixes #4280 (removing this flag giving qTox on Windows able to start properly), another part fixes my mistake in #4258 (strmiids still needed for
linking, but previous searching of this libstrmiids.a wasn't include, for example, '/mingw32/i686-w64-mingw32/lib'. So I just add this lib to $ALL_LIBRARIES,
because it exists in system by default).
