Drop the trailing colon.

If you provide a colon, you MUST also provide a group spec. Per 'chown
--help', the syntax is:
chown [OPTION]... [OWNER][:[GROUP]] FILE...
so these are valid:
chown 1001 /tmp/bla # change owner only
chown :1001 /tmp/bla # change group only
chown 1001:1001 /tmp/bla # change both
but this is invalid:
chown 1001: /tmp/bla # '' is not a valid group
