Remove dummy librariessubmit/tizen/20200706.084419accepted/tizen/unified/20200707.140939

Following commit removes dummy EGL/GLES libraries and implements
discovery of /dev/yagl in libEGL.so.

If /dev/yagl is missing (ex. there is no host GPU available), libEGL.so will
fail any EGL function. This will make it impossible to create a functioning
GLES context, which will make GLES functions exit early, on YAGL_GET_CTX() calls.
