dracut will process conf files with bash, and in fact it's common to use idioms like += in conf files for string concatenation. The current grep usage in the Makefile won't catch all possible valid 'drivers' variable cases. Instead, use bash to parse and echo the 'drivers' content Fixes: #356 Signed-off-by: Cole Robinson <crobinso@redhat.com>
