[bug#54713] [PATCH] gnu: linux: Allow kconfig options to be strings

[antlers]

* gnu/packages/linux.scm (config->string): add a clause handling strings

Allows for the declarative configuration of kconfig options which accept
strings, such as CONFIG_MODULE_SIG_KEY.

I've enclosed the given string in quotes, but don't do any kind of
escaping. See the kernel mailing list for the current state of escaped
strings upstream:

https://patchwork.kernel.org/project/linux-kbuild/patch/1431003982-992-1-git-send-email-sr@denx.de/

Apologies to those with double-quotes or backslashes in their
CONFIG_SYSTEM_*_KEYS.
