[PATCH 24/86] perf trace beauty: Export the fd beautifier for use in more places

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Now that the beautifiers are being split into multiple source and object
files, we will need more of them exported, do it for the 'fd' one, will
be used to augment the return of some syscalls that may return an 'fd',
such as fcntl(fd, F_DUPFD).
