base: fix xx-info failing on macOS, set default vendor to "unknown"

macOS doesn't have a /etc/os-release, which caused the script to fail when running on the host. Also adds detection if /etc/os-release exists, and setting vendor to "unknown" as a default. Signed-off-by: Sebastiaan van Stijn <[email protected]>
