Removes error and die in multithreaded forks

Ryan Houdek d0de92f97a Removes error and die in multithreaded forks 
This can result in some terrible behaviour if something doesn't
immediately execve once it forks. Allow it instead of crashing out
though.

Stefanos Kornilios Mitsis Poiitidis bddc0a3445 Merge pull request #392 from Sonicadvance1/more_syscalls2 
Spam out a wackload more syscalls
 2020-09-16 20:55:51 +03:00
Ryan Houdek ddecec12ec Spam out a wackload more syscalls 
Almost all of these end up being simple passthrough.
This covers most syscalls, the remaining ones are signal related, exec
related, or rseq required.

All of these syscalls exist prior to Linux 5.0. We are using these with
the expectation still that the host Linux implementation is 5.0 or
higher.
Once we implement newer syscalls we will need to start checking for host
Linux version. We don't really have a care about devices shipping older
4.x kernels atm.
