build-sys: correctly search for gnu-efi header

When the user provides the --with-efi-includedir we incorrectly search
for the header at /usr/include not the provided location. This patch
changes the check to use the provided value so that non-standard header
locations are supported.

This situation occurs commonly when cross-compiling systemd because the
GNU EFI headers and library will not be installed into the root
locations but highly likely a temporary system root.
