macOS Uninstall PCP

[tallpsmith]

We currently bundle an uninstall-pcp script as part of the package. Running it I get this:

cp@pcps-Virtual-Machine pcp % sudo /usr/local/libexec/pcp/bin/uninstall-pcp
Password:
Are you sure you want to uninstall PCP? [y/n] y

That script needs some love to modernize it. A few notes from scanning it:

• it hard-codes /tmp use and uses predictable file names, better to use mktemp(1) (see pcp(1) script for example)
• not sure the interactive echo/read aspects are useful, esp. if this is to become something automated
• obviously the references to /Library/StartupItems need to be updated, and its missing pmie and pmproxy there
• the removal of files/directories we installed is a little dated now because we install all paths needed (incl. /usr/local/bin etc) - a bit more intelligence is needed here to only remove files and directories specific to PCP (restricting to paths that include "/pcp/" might be a workable heuristic)
