Support verifying the value of strings (and not just y/m/n settings)

Becuase of kpatch-inclusions having quotes around the string, but the
value from `scripts/config` having the quotes stripped, the comparison
fails due to one side having quotes but the other side not having
quotes.

This effectively adds support for setting string kconfigs in
kconfig-inclusion.
