elog: enable by default for CHROMEOS

elog breaks the build if ELOG_FLASH_BASE isn't configured -
and CHROMEOS isn't enabled, since with Chrome OS builds, it
just uses fmap to find out the base.

So it makes sense to enable it on all Chrome OS builds - if
the code never uses it, the linker will drop it soon enough.
