[BOLT] Handle __uniq suffix added by -funique-internal-linkage-names
In profile matching, if `.__uniq` suffix added for internal linkage
symbols with `-funique-internal-linkage-names` prevents BOLT from
matching to a binary function, try to strip the suffix and perform
fuzzy name matching.
Follow-up to D124117.
