module: add helper function for reading module_buildid()
[ Upstream commit acfdbb4ab2910ff6f03becb569c23ac7b2223913 ]
Add a helper function for reading the optional "build_id" member of struct
module. It is going to be used also in ftrace_mod_address_lookup().
Use "#ifdef" instead of "#if IS_ENABLED()" to match the declaration of the
optional field in struct module.
