pcpqa common.rc: Don't suppress sudo unless $PCP_DIR is our own

The pcpqa testsuite needs to do sudo-root kinds of operations
periodically, but defeats its own capabilities if it detects $PCP_DIR
set.  However, this is too much.  There may be root/system-wide pcp
installations at some $PCP_DIR location.  So add a heuristic that we
keep sudo for set $PCP_DIR *unless* $PCP_DIR is owned by the invoking
user.
