[OE-core] [PATCH] Fix: chown: Use double colon for OWNER:GROUP

[Kosta Zertsekel]

Rationale - excerp from `info chown`
====================================

OWNER‘:’GROUP
     If the OWNER is followed by a colon and a GROUP (a group name or
     numeric group ID), with no spaces between them, the group ownership
     of the files is changed as well (to GROUP).

   Some older scripts may still use ‘.’ in place of the ‘:’ separator.
POSIX 1003.1-2001 (*note Standards conformance::) does not require
support for that, but for backward compatibility GNU ‘chown’ supports
‘.’ so long as no ambiguity results.  New scripts should avoid the use
of ‘.’ because it is not portable, and because it has undesirable
results if the entire OWNER‘.’GROUP happens to identify a user whose
name contains ‘.’.
