Subject: [PATCH] build: Pick first field in ID_LIKE

CentOS Stream has:

ID_LIKE="rhel fedora"

which confused the existing script.  If there are multiple "likes"
arbitrarily pick the first one in the list.

Fixes: commit 63b722b6c094f3a35a5e72f0ae3236a58ddda110
(cherry picked from commit 7afbf5ee4415f6fa2553898d3af238e794062096)
