loader.so: patched `ps` complains about `SIGCHLD`

[jm33-m0]

Describe the bug

When using get_persistence -> patcher, patched ps binary will run emp3r0r's agent every time it runs. Since agent runs in daemon mode (it exits and relaunches), ps catches SIGCHLD and complains.

To Reproduce

Steps to reproduce the behavior:

1. use get_persistence
2. set method patcher and run
3. ps -ef | grep 123

Expected behavior

No error should show up, users should not notice anything wrong with ps
