Mark _init and _fini for --gc-sections
gold marks _init and _fini via symbol, ld marks them via section
(default scripts set .init and .fini section KEEP). This makes it
possible for people to write their own _init and not bother to put the
function into the right section.
PR ld/18223
* ldlang.c (lang_process): Add _init and _fini to gc_sym_list.
