usr/include/Makefile: add linux/nfc.h to the compile-test coverage

usr/include/Makefile: add linux/nfc.h to the compile-test coverage

BugLink: https://bugs.launchpad.net/bugs/1959879
commit 10756dc5b02bff370ddd351d7744bc99ada659c2 upstream.

As linux/nfc.h userspace compilation was finally fixed by commits
79b69a83705e ("nfc: uapi: use kernel size_t to fix user-space builds")
and 7175f02c4e5f ("uapi: fix linux/nfc.h userspace compilation errors"),
there is no need to keep the compile-test exception for it in
usr/include/Makefile.
