grep: Fix shell after autotools changes

After changing autotools.bbclass, CONFIG_SHELL setting no longer works
resulting in:

grep-3.4-r0 do_package_qa: QA Issue: /bin/fgrep.grep contained in package grep requires /bin/bash, but no providers found in RDEPENDS_grep? [file-rdeps]

The script can use /bin/sh so set this specifically using sed since we
want to use a consistent shell for the rest of the build but not have
the specific bash dependency.
