selftests/bpf: Support out-of-tree vmlinux builds for VMLINUX_BTF
Add detection of out-of-tree built vmlinux image for the purpose of
VMLINUX_BTF detection. According to Documentation/kbuild/kbuild.rst, O takes
precedence over KBUILD_OUTPUT.
Also ensure ~/path/to/build/dir also works by relying on wildcard's resolution
first, but then applying $(abspath) at the end to also handle
O=../../whatever cases.
