We've been creating and linking against a library called "libvboot_host.a"
for two different reasons. The main purpose is to build the vboot_reference
tools found in the utility/ directory. But there are some external userspace
programs that would also like to use some functions in this library.
This change establishes libvboot_host.a as the library for use by external
userspace programs only, and creates a new libvboot_util.a library that's
only used inside this source tree to build the vboot utilities.
