[coreboot] removal of svn:externals in v2's util/

[Patrick Georgi]

Hi,

after a quick poll on IRC on what to do with the svn:externals in util/,
we pretty much agreed that removing them is the way to go.

People who need those tools can still fetch them at the original
location in the repository, and already checked out trees will continue
to carry those directories.

If you have any good reason why this shouldn't happen, or that another
course of action (eg. moving the tools into the coreboot v2 repository,
so everyone gets them), speak up.

Time's up at 20:00 CEST

Regards,
Patrick
