ci: reduce ASLR entropy

Browse source 
The latest GH Action runners started using 32-bit entropy for ASLR,
which makes it incompatible with llvm-14. This was fixed in later llvm
releases, but these aren't available on Ubuntu Jammy (22.04). Let's
reduce the ASLR entropy to 28-bit, which should make llvm happy again,
until the issue is resolved.
