selftests/bpf: Select CONFIG_FUNCTION_ERROR_INJECTION

Browse Source 
BPF selftests require CONFIG_FUNCTION_ERROR_INJECTION to work. However,
CONFIG_FUNCTION_ERROR_INJECTION is no longer 'y' by default after recent
changes. As a result, we are seeing errors like the following from BPF CI:

   bpf_testmod_test_read() is not modifiable
   __x64_sys_setdomainname is not sleepable
   __x64_sys_getpgid is not sleepable

Fix this by explicitly selecting CONFIG_FUNCTION_ERROR_INJECTION in the
selftest config.

Fixes: a4412fdd49 ("error-injection: Add prompt for function error injection")
