Cygwin: dll_list: query dll file id at load time
NtQueryVirtualMemory for MemorySectionName does not reliable return the
changed dll file name when another process does move the file around,
and we may end up creating forkable hardlinks to wrong dll files.
So query the file id when loading the dll rather than before fork.
