Subject: [PATCH] Revert unnecesary lcase in ds-identify (#978)

This patch reverts an unnecessary lcase optimization in the
ds-identify script. SystemD documents the values produced by
the systemd-detect-virt command are lower case, and the mapping
table used by the FreeBSD check is also lower-case.

The optimization added two new forked processes, needlessly
causing overhead.
