[PATCH] tools: Ensure tools copy of linux/filter.h exports the UAPI

Normally when there is an include/foo.h and an include/uapi/foo.h the
non-UAPI copy includes the UAPI copy.  This is the case for the in
kernel copy of linux/filter.h but not for the copy in tools/ which
results in build breaks for the newly added arm64
seccomp_ptrace_x0_bypass selftest.  Add an explicit include of the uapi
to fix the test and avoid future surprises.

Fixes: 2fcbc4adf997 ("kselftest/arm64: Add seccomp ptrace x0 bypass test")
Fixes: f143c11bb7b9 ("tools: bpf: Use local copy of headers including uapi/linux/filter.h")
