selftests/bpf: Fix bpf selftest build error

Browse Source 
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 97d06802d1 ("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: 97d06802d1 ("sysfs: constify bin_attribute argument of bin_attribute::read/write()")
