contrib: remove mergetools.hgrc premerge=False for Beyond Compare and Araxis

There can be good reasons to disable premerge no matter which merge tool is
used. Most tools will do just fine without premerge and handle the simple
merges more or less automatic and silent. We _could_ thus disable premerge for
most tools. But without premerge, the merge tool will be launched for each file
- that makes it a slow and expensive process to perform big simple merges. It
  is thus better to consistently stick to the default premerge=True.

The mergetools.hgrc configuration for most tools implicitly use the default
premerge=True but Araxis and the Linux entry for Beyond Compare had
premerge=False. These lines has been removed.

These settings were introduced by 6b354a763617 without further explanation of
why they should be good.

(We have seen some crashes on Windows with Araxis where a merge failed after a
lot of Araxis flashing. I haven't been able to reproduce it and do not know
exactly what happened. Enabling premerge avoids the problems.)
