Subject: [PATCH] platform/x86: dell-smbios: Match on www.dell.com in OEM strings too

Sergey reported that some much older Dell systems don't support
the OEM string "Dell System" but instead supported www.dell.com
in OEM strings.

Match both of these to indicate that this driver is running on
a Dell system.
