loader: set DEFAULT_VK_{DRIVER,LAYER}S_PATH to "" on Linux

Browse Source 
When loader_get_fullpath() gets an empty string as the 'dir' parameter,
it immediately writes out the original, unexpanded filename. Setting
the default drivers and layers paths to an empty string on Linux will
allow the unmodified filenames to be passed to dlopen(3) without having
to maintain a separate code path for Windows.

Now that there is no longer a default path for drivers or layers on
Linux, ${CMAKE_INSTALL_LIBDIR} no longer needs to be baked into the
loader binary. Note that any ICDs or layers that are currently getting
installed to the previous default paths (e.g. /usr/lib/vulkan/icd or
/usr/lib/vulkanlayer) will not be discoverable when specified as plain
filenames, unless these directories happen to be configured in the
loader's search path on the system in question.
