loader: introduce the loader util lib

All the various window system integration layers duplicate roughly the
same code for figuring out device and driver name, pci-id's, etc.  Which
is sad.  So extract it out into a loader util lib.

v2 (Emil)
* Separate the introduction of libloader from the code de-duplication.
* Strip out non-pci devices support.
* Add scons + Android build system support.
* Add VISIBILITY_CFLAGS to avoid exporting the loader funcs.

v3 (Emil)
* PIPE_OS_ANDROID is undefined at this scope, use ANDROID
* Make sure we define _EGL_NO_DRM when building only swrast
