meson: bpf: propagate 'sysroot' for cross compilation

During cross-compilation of systemd, the compiler used to build the bpf's needs to be pointed at the correct include searchpath. Which can be done by passing the corresponding directory in through the cflags; for example in yocto/bitbake this would work: CFLAGS += "--sysroot=${STAGING_DIR_TARGET}" Signed-off-by: Johannes Schneider <[email protected]>
