selftests/mm: remove flaky header check
Commit 96ed62ea0298 ("mm: page_frag: fix a compile error when kernel is
not compiled") introduced a check to avoid attempting to build the
page_frag module if <linux/page_frag_cache.h> is missing.
Unfortunately this check only works if KDIR points to /lib/modules/... or
an in-tree kernel build. It always fails if KDIR points to an out-of-tree
build (i.e. when the kernel was built with O=... make) because only
generated headers are present under $KDIR/include/ in that case.
A recent commit switched KDIR to default to the kernel's build directory,
so that check is no longer justified.
