[PATCH bpf v1 0/7] selftests/bpf: Add and use strscpy()

[Ihor Solodrai <ihor.solodrai@linux.dev>]

This series introduces a simplified implementation of strscpy() to
selftests/bpf and then replaces strcpy/strncpy usages across the tests
with it.

For context see a discussion that prompted this series [1].
