[PATCH] fixed typos on selftests/bpf

[Taichi Nishimura <awkrail01@gmail.com>]

I run spell checker and found typos in selftest/bpf/ files.
Fixed all of the detected typos.

This patch is an extra credit for kselftest task
in the Linux kernel bug fixing spring unpaid 2023.

Best regards,
Taichi Nishimura
