buildstats.py: close /proc/pressure/cpu file descriptor

Browse Source 
Use python 'with' symantics to ensure that the /proc/pressure/cpu file
descriptor used in SystemStats init is closed. Previously, this would
lead to a single file descriptor being leaked. For example:
   ResourceWarning: unclosed file <_io.BufferedReader name='/proc/pressure/cpu'>
