Add missing <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].
