tests: Add library to include path when used as submodule
Some tests use internal-only header files, which are stored in the
'library' folder, and therefore need the library folder passed in on the
include path. For non-submoudle builds, this is set globally in the
top-level CMakeLists.txt file. For submodule builds, this is set through
target includes to a path only meaningful when Mbed Crypto is built as a
submodule.
