Avoid undefined non-weak-symbol for libglapi in dri drivers
This issue was initialy reported in:

This doesn't lead to issue (probably) because dri drivers are linked to
libGL.so which is linked to libglapi, so the symbols are resolved at runtime
dynamically.
But with glvnd enabled mesa, the libglvnd's libGL isn't linked to libglapi
anymore (libGLX_mesa is). This lead process like Xorg server to miss the symbol
resolution and fail to load the appropriate DRI driver.
The suggested fix links to a shared libglapi everywhere (not only on ANDROID).</pre>
