glapi: Correct prerequisites for gl_and_glX_API.xml
glapi: Correct prerequisites for gl_and_glX_API.xml

The indirect_dispatch.h and indirect_table.c source files use
gl_and_glX_API.xml in their generation rather than glX_API.xml, but it
wasn't listed in their prerequisites. In turn, gl_and_glX_API.xml uses
glX_API.xml, but this is already listed in $(COMMON_GLX).
