pjproject: Fix race condition when building with parallel make

Pjproject makefiles miss some dependencies which can cause race
conditions when building with parallel make processes. This patch
adds such dependencies correctly.

Subject: [PATCH] Fix race condition in parallel builds (#2426)
* Some targets residing in `OBJDIRS` are missing a dependency on that directory, which results in a race condition, causing build to fail sometimes due to the directory not existing when running parallel builds.
* The `PJSUA_LIB` variable is not defined anywhere, resulting in an empty value, and no correct dependency on the pjsua shared library for `pjsua2`. The correct variable seems to be `PJSUA_LIB_LIB`, defined at the start of this same `Makefile`.
