[PATCH] tools: Fix virt-host-validate SEV detection

[Jim Fehlig]

virt-host-validate checks if AMD SEV is enabled by verifying
/sys/module/kvm_amd/parameters/sev is set to '1'. On a system
running kernel 5.13, the parameter is reported as 'Y'. To be
extra paranoid, add a check for 'y' along with 'Y' to complement
the existing check for '1'.
