when trying to compile rte_mpls with pedantic enabled,
on old compilers like 4.8 it will complain about bit field definition.
error: type of bit-field 'bs' is a GCC extension [-Werror=pedantic]
error: type of bit-field 'tc' is a GCC extension [-Werror=pedantic]
error: type of bit-field 'tag_lsb' is a GCC extension [-Werror=pedantic]
This fixes the compilation error by adding extension to the header
definition.
Fixes: e480cf487a ("net: add MPLS header structure")
