Added get_regvals() function that uses the new API for retrieving

register values from processes belonging to the same user. Root
can retrieve register values from any running process.
Bumped version to 1.2.2, this is the VEOS version which introduced
the ve_get_regvals() function.
Changed setup.py to install only the veosinfo.so file into the
Python site_packages directory, not an entire package (directory).
