[PATCH v2 1/9] oe-selftest: devtool: use stat for reading user/group names in ide-sdk tests

[AdrianF <adrian.freihofer@siemens.com>]

From: Adrian Freihofer <adrian.freihofer@siemens.com>

On some systems, ls truncates long user and group names, which causes the
ownership check to fail. For example:

AssertionError: Regex didn't match:
  '^-.+ cmake-example cmake-example .+ /etc/cmake\\-example\\.conf$' not found in
  '-rw-r--r--    1 cmake-ex cmake-ex        83 Mar  9  2018 /etc/cmake-example.conf'

Use "stat -c '%U %G'" instead, which always returns the full user and group
names regardless of terminal width or system configuration.
