p11-kit: fix build without qemu-usermode

If qemu-usermode is not available then p11-kit fails to configure:

  meson.build:313:24: ERROR: Can not run test applications in this cross environment.

This has already been fixed upstream, so backport the patches.

+Subject: [PATCH] Check for GNU strerror_r using the compiler only
+
+The new test that was added to distinguish GNU/XSI strerror_r ran a
+compiled program, which doesn't work when cross-compiling. The only
+difference at compile time is that the GNU version returns char * and
+the XSI version returns int, so detect it by compiling a program that
+dereferences the return value.

+Subject: [PATCH] Define _GNU_SOURCE when testing for strerror_r
+
+The Meson check for GNU/XSI strerror_r didn't inherit the project
+options that include _GNU_SOURCE (unlike the autoconf version), so the
+result didn't match how the code that uses it will be compiled. Add
+_GNU_SOURCE explicitly as with the following checks.
