Tim Schumacher 96b4f2e974 selinux: Chain up tool resolving errors in install_policy.sh 
[ Upstream commit 6ae0042f4d3f331e841495eb0a3d51598e593ec2 ]

Subshell evaluations are not exempt from errexit, so if a command is
not available, `which` will fail and exit the script as a whole.
This causes the helpful error messages to not be printed if they are
tacked on using a `$?` comparison.

Resolve the issue by using chains of logical operators, which are not
subject to the effects of errexit.
