Patch to clarify readlink(1) man page

[Bruce Jerrick]

The --canonicalize options in the readlink(1) man page would be much
easier to keep straight if they
were in least-to-most restrictive order, rather than alphabetic order.

Here is a diff that changes it (to be applied to the uncompressed
/usr/share/man/man1/readlink.1.gz);
it was generated from Fedora 30 Updates coreutils-common-8.31-2.fc30 .
The result is this order:

    -m, --canonicalize-missing
    -f, --canonicalize
    -e, --canonicalize-existing
