Remove mapper nice priority

This is a revert of eff3d02a180ef60102f1f25d765b2ddf72831be3
A direct revert is not possible due to our subtree refactoring

Prioritizing one application over another seems to cause more
problems then it solves. In this case it appears that mapper
can starve other process's in which mapper depends on responding.
So that dependent process times out, restarts, which then causes
the whole cycle to start over.

Hoping this is the fix to openbmc/openbmc#3369 but will require
some testing.

Tested: George was kind enough to run this through some BMC reboot
tests and a regression bucket. openbmc/openbmc#3369 did not recreate
but not willing to declare success yet with that bug.
