Original GitHub issue: https://github.com/netblue30/firejail/issues/5122

Describe the solution you'd like

choom 123

in the profile will write 123 into /proc/<pid>/oom_score_adj

Additional context

man 1 choom and man 5 proc
This should be done unprivileged because writing negative numbers is a privileged task.

I like the idea!

* This should be done unprivileged because writing negative numbers is a privileged task.

(except the jail is started by root, similar to --nice)

undefined reference to `oom_set'

@netblue30 looks like you forgot to commit oom_set.

Shell completions and vim syntax files need to be updated as well. And a profile command would be nice too.
