[PATCH v2 0/3] selftests/bpf: A few edge case fixes

["Ricardo B. Marlière" <rbm@suse.com>]

Hi,

Please consider merging the following fixes, found by means of targeting
BPF selftests through openQA [1].

[1]: e.g. https://openqa.opensuse.org/tests/6087703

1/4 ("libbpf: Search /lib64 and /lib in resolve_full_path()")
- Hit by testing an older SLES root filesystem.

2/4 ("selftests/bpf: Fix lsm_bdev dev_t encoding mismatch")
- https://openqa.opensuse.org/tests/6087703/logfile?filename=test_progs.tap.txt#line-2706

3/4 ("selftests/bpf: Install resolve_btfids.test.o.BTF where the test expects it")
- https://openqa.opensuse.org/tests/6087703/logfile?filename=test_progs.tap.txt#line-3332

4/4 ("selftests/bpf: Install bpftool where test_progs expects to find it")
- https://openqa.opensuse.org/tests/6087703/logfile?filename=test_progs.tap.txt#line-806
- https://openqa.opensuse.org/tests/6087703#step/test_bpftool_build_sh/1
- https://openqa.opensuse.org/tests/6087703#step/test_doc_build_sh/1

The build process is done at runtime with BPF_STRICT_BUILD=0:
https://openqa.opensuse.org/tests/6087703/logfile?filename=serial_terminal.txt#line-1937
