selftests/bpf: Fix bpf selftest build error
On linux-next, build for bpf selftest displays an error due to
mismatch in the expected function signature of bpf_testmod_test_read
and bpf_testmod_test_write.
Commit 97d06802d10a ("sysfs: constify bin_attribute argument of bin_attribute::read/write()")
changed the required type for struct bin_attribute to const struct bin_attribute.
To resolve the error, update corresponding signature for the callback.
Fixes: 97d06802d10a ("sysfs: constify bin_attribute argument of bin_attribute::read/write()")
