Error out when trying to set PTRACE_O_TRACESECCOMP under ptrace emulation. #311

Closed jzakrzew closed 2 years ago

proot currently does not even try to handle seccomp traps when running ptrace emulation. Returning an error is better than misleading the ptracer into expecting seccomp events.

In conjunction with PR #308, this (sort of) fixes test-230f47ch.

This also seems to fix issue #310
