[Thomas:
 - fix LICENSE variable, as noticed by Yegor
 - fix alphabetic ordering in package/Config.in
 - add missing select BR2_PACKAGE_LIBDRM in Config.in, and the
   corresponding dependencies
 - add missing depends on BR2_PACKAGE_HAS_UDEV in Config.in
 - use gbm.h as license file, instead of extracting the first 26 lines
   of the header file]
