Use "pe:remote:<task>"instead of "pe:local_<task>"

On some historic Bad Idea Monday we decided that PE devs would find it easier
to just do "pe:deb" instead of "pe:remote:deb", even though the remote task is
what they would be doing. To accommadate this, we made "pe:deb" and such point
to the remote tasks that operate over ssh, and the local tasks we called
"pe:local_<task>". This diverged completely from the paradigm established for
foss, and was also completely nonsensical. This commit rips all that trash out,
and updates the pe tasks to either be local (pe:deb) or remote (pe:remote:deb).
This will help enormously in porting the new jenkins-dynamic workflow over to
PE, as well as helping me recover my sanity every time I look at these tasks.
