Lorenz Bauer 8a98ae12fb bpf: Exempt CAP_BPF from checks against bpf_jit_limit
When introducing CAP_BPF, bpf_jit_charge_modmem() was not changed to treat
programs with CAP_BPF as privileged for the purpose of JIT memory allocation.
This means that a program without CAP_BPF can block a program with CAP_BPF
from loading a program.

Fix this by checking bpf_capable() in bpf_jit_charge_modmem().

Fixes: 2c78ee898d ("bpf: Implement CAP_BPF")
