[OE-core] [PATCH 2/2] wic: _exec_cmd: produce error if exit code is not 0

[Ed Bartosh]

Current code doesn't always show error output of the
external command and even ignores non-zero exit code.

Moved checking of exit code value to the lowest level
possible: to _exec_cmd. This should make wic to always
check exit code of the external command and issue
an error if it's not 0.
