Changed order of uid/gid to match POSIX `ls -l`.
This changes the output order of lines from gfal-ls -l
to match the ordering of POSIX ls(1)
output. From the standard:
If the -l option is specified without -L, the following information shall be written:
"%s %u %s %s %u %s %s\n", <file mode>, <number of links>,
<owner name>, <group name>, <number of bytes in the file>,
<date and time>, <pathname>
