Subject: [PATCH] dell-smbios-base: Consider Alienware a Dell system

Alienware has been a subsidiary of Dell since 2006.

2020 Alienware laptop:
$ sudo dmidecode | head -3
# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 3.2.0 present.
$ sudo dmidecode | grep -A 29 "OEM Strings"
OEM Strings
	String 1: Alienware
	String 2: 1[099B]
	String 3: 3[1.0]
	String 4: 4[0001]
	String 5: 5[0000]
	String 6: 6[D0, D4, D8, DA, DE]
	String 7: 7[]
	String 8: 8[]
	String 9: 9[]
	String 10: 10[1.3.0]
	String 11: 11[]
	String 12: 12[]
	String 13: 13[P38E002]
	String 14: 14[0]
	String 15: 15[0]
	String 16: 16[0]
	String 17: 17[0000000000000000]
	String 18: 18[0]
	String 19: 19[1]
	String 20: 20[]
	String 21: 21[]
	String 22: <BAD INDEX>
	String 23: <BAD INDEX>
	String 24: <BAD INDEX>
	String 25: <BAD INDEX>
	String 26: <BAD INDEX>
	String 27: <BAD INDEX>
	String 28: <BAD INDEX>

2013 Alienware laptop:
OEM Strings
        String 1: Dell System
        String 2: 1[05AA]
        String 3: 14[2]
        String 4: 15[0]
        String 5: String5 for Original Equipment Manufacturer

Don't know when the OEM String changed.
Change tested in the 2020 laptop, loads dell_smbios without further
issues.

Thanks,
        Gerardo
