CHROMIUM: x86: defconfig: enable CONFIG_DMI_SYSFS

Userland SMBIOS parsing utilities such as mosys and dmidecode
currently open /dev/mem to find the SMBIOS entry point and parse DMI
information.  The security team has advised us this puts Chrome OS
at-risk for an attack, and we should look at using the sysfs DMI
entries.

This commit enables CONFIG_DMI_SYSFS, which is necessary to expose
entries under /sys/firmware/dmi/entries/*.

BUG=chromium:1080674
TEST=observe presence of entries under /sys/firmware/dmi/entries/*
