libcamera: process: Fail loudly on isolate

Add an error debug message when disassociating part of a process
execution context using unshare fails.

As this is currently used to isolate a child process which is
immediately terminated silently if unshare fails, add a debug printout
and propagate up the error code to make the failure more visible.
