test/others: refactor loop process

There are several problems with the loop.sh script. First, the code is
duplicated across tests in the so-called 'othres' category. Second, we
need to run it with the 'setsid' utility to make sure that it runs in
a new session. Third, we have to redirect the standard file descriptors
and use the '&' operator to make it run in the background. Finally,
obtaining the PID of the 'loop.sh' process resulted in race condition.

In this patch we replace the loop.sh script with a program that would
address all problems mentioned above. The requirements for this program
are as follows.
- It must be reusable across tests
- It must start a process that is detached from the current shell
- It must wait for the process to start and output its PID
