Android: gallium_dri: pass dri.sym to linker

Browse Source 
Pass the dri.sym version script to the linker. This ensures only
explicitly exported symbols are exported and shrinks the library by up
to 60KB.

HAVE_DLADDR also needs to be set so that __driDriverExtensions is defined.

We need to pass "--undefined-version" because the Android build system
sets --no-undefined-version by default and we get an error on
driver specific symbols if those drivers are disabled without the option.
