kconfig_lint: merge 'git grep' and 'grep' exclude dir and files

The code had originally been using standard grep to look through the
coreboot tree for Kconfig symbols.  When this was switched to git grep,
the --exclude-dir options didn't work, and nothing was added to exclude
the directories that shouldn't be searched for symbols.  This resulted
in invalid warnings as it searched directories that had Kconfig symbols
for other projects.

This merges the exclusion list for both the regular and git versions
of grep for consistent behavior.
