scripts/check_format.sh: fix naming convention check.

Browse Source 
I had previously implemented a portion of the naming convention
check that looked for symbols that had been moved by performing
two checks:

git diff commit1 commit2 -- libname | grep for added function
git diff commit2 commit1 --libname | grep for added functions

and then subtracting the values returned by the second check from
the values returned by the first check. That works as long as the two
diffs are reciprocal (i.e. the first diff is a mirror image of the
second). However, this has proven to not be the case.

This change fixes that check by performing the smae diff twice and
grepping for removed functions the same time.
