  [BOLT][runtime] fix readlink bound check in getBinaryPath. (#191666)

Ret was uint32_t truncating the uint64_t __readlink return, and was
compared against the unrelated getdents64 BufSize (1024) instead of
sizeof(TargetPath) (NameMax, 4096). A truncated readlink of exactly
NameMax bytes also wrote one byte past TargetPath.
