libchromeos: Don't import from libchromeos/chromeos.

When importing a libchromeos header in libchromeos or in another
package, don't prefix the import path with libchromeos/.

The headers for the libchromeos shared library are installed in
/usr/include/chromeos.
Using libchromeos/chromeos/* will use the headers from
src/platform2/libchromeos which may not match the .so.

BUG=None
TEST=cros_workon-gizmo start libchromeos germ feedback &&
./build_packages --board=gizmo
TEST=`cros_run_unit_tests --board=gizmo --packages "libchromeos germ
feedback"` succeeds.
