oprofile: Determine the root home directory dynamically
This commit detects the root home directory dynamically with changes to
the opcontrol script and the oprofile gui app source.
The commit replaces an earlier fix that detected and adjusted a
'non-standard' root home directory at build time. The advantage of this
patch is that the oprofile tools are adjusted to the current run-time
path to ~root, not the build time path.
