modpost: get the *.mod file path more simply
get_src_version() strips 'o' or 'lto.o' from the end of the object file path (so, postfixlen is 1 or 5), then adds 'mod'. If you look at the code closely, mod->name already holds the base path with the extension stripped. Most of the code changes made by commit 7ac204b545f2 ("modpost: lto: strip .lto from module names") was actually unneeded. sumversion.c does not need strends(), so it can get back local in modpost.c again.
