libsemanage/tests: make tests standalone

In order to run libsemanage tests, libsepol and libselinux source
directories need to exist next to libsemanage source directory. This
prevents tests to be run when using the released package.

As libsemanage tests only use public API of libselinux and libsepol,
link with the shared objects which are likely to be installed on the
system (or at least present in $DESTDIR).

While at it, drop TESTSRC variable as it was used to find libsemanage
internal headers but not the tested library (libsemanage.a). Moreover
add ../src/libsemanage.a to the target dependencies of the test
executable in order to rebuild it after libsemanage.a has been updated.
