meta: Fix return value checks from subprocess.call()'s
Python function subprocess.call() returns the return value of the
executed process. If return values are not checked, errors may
go unnoticed and bad things can happen.
Change all callers of subprocess.call() which do not check for
the return value to use subprocess.check_call() which raises
CalledProcessError if the subprocess returns with non-zero value.
https://docs.python.org/2/library/subprocess.html#using-the-subprocess-module
All users of the function were found with:
$ git grep "subprocess\.call" | \
egrep -v 'if.*subprocess\.call|=\
+subprocess\.call|return.*subprocess\.call'
Tested similar patch on top of yocto jethro. Only compile tested
core-image-minimal on poky master branch.

Added return code checking to do_diffconfig. Although the change is
well intentioned, it isn't correct in this instance since 'diff' returns
'1' to indicate that there are differences in the files .. and not as
an error code.
subprocess.check_call() flags this as an error and the routine aborts.
We are already checking the inputs, and in fact already know there's a
diff in the files before we even make the call, so there's no need to
look for an error in this case.
Putting back subprocess.call() restores the routine to working order.
