package/gcnano-binaries: create symlinks for libGLESv2 and libGLESv1_CM.so

Browse Source 
At least libepoxy, a user of OpenGL ES, expects libraries to be
available as libGLESv2.so.2 and libGLESv1_CM.so.1. While other OpenGL
implementations comply with this, gcnano-binaries does not, and
installs its libraries directly as .so, without any ABI version,
causing runtime failures with libepoxy or SDL2, as it tries to
dlopen() the OpenGL ES libraries with their ABI suffix.

See for example the libepoxy code:

  https://github.com/anholt/libepoxy/blob/master/src/dispatch_common.c#L191

Fix this issue by adding the relevant symlinks.
