test: resolve process.setegid error for nobody on ubuntu
When the tests are run as root in Ubuntu, process.setegid is called with 'nobody' as an argument. This throws an error in Ubuntu. This is because in Ubuntu the equivalent of 'nobody' group is named as 'nogroup'.
This commit sets egid to 'nobody' first and if it throws a group id does not exist
error, it attempts to set egid to 'nogroup'. If it still
causes an error, the error is thrown.
