Describe the bug

When SELinux is Enforcing, scripts started by systemd need the initrc_exec_t context set. It is not currently.

To Reproduce

Steps to reproduce the behavior:

1. Have SELinux Enforcing;

2. Add a runner;

3. Run ./svc.sh install

4. Observe that systemd failed to start the script:

   sudo grep -i denied /var/log/audit/audit.log|grep -i svc|tail -1|fold -s

   type=AVC msg=audit(1642053001.589:304): avc:  denied  { execute } for  
   pid=14114 comm="(unsvc.sh)" name="runsvc.sh" dev="vda1" ino=25325969 
   scontext=system_u:system_r:init_t:s0 
   tcontext=unconfined_u:object_r:user_home_t:s0 tclass=file permissive=0
   

Expected behavior

• systemd should be able to start the script.

Runner Version and Platform

• Version: 2.278
• OS: Linux (x64)
