Add missing <linux/string.h> include for strcmp.

Clang 16 makes -Wimplicit-function-declaration an error by default. 
Unfortunately, out of tree modules may use this in configure scripts,
which means failure might cause silent miscompilation or misconfiguration.

For more information, see LWN.net [0] or LLVM's Discourse [1], gentoo-dev@ [2],
or the (new) c-std-porting mailing list [3].
