hybris: common: mm: search lib in library path if opening directly fails.

On some device, a binary blob call dlopen with "egl/blah.so". The
correct behavior (and current code's behavior) is to open the library
directly on that path (relative to working directory) and don't look in
library path.

But the sad truth of life is, some binary blob rely on old behavior
which will not open the library directly if the path doesn't start
with '/'. As the library is actually reside in /system/vendor/lib/egl/,
the code will work with old behavior and not new behavior.

This commit makes linker search for library in library path if it can't
open library directly, which is the behavior of Android 5.0's linker.
This will let those libraries work.

This is the reference of this behavior:
