glamor: free the link log on shader link failure

Browse source 
glamor_link_glsl_prog() retrieves the GL link log when program linking
fails and prints it with ErrorF(), but did not free the allocated log.

  Direct leak of 51 byte(s) in 1 object(s) allocated from:
    #0 in malloc
    #1 in glamor_link_glsl_prog ../glamor/glamor_core.c:105
