filemerge: make `_maketempfiles()` more reusable

`_maketempfiles()` is very specialized for its current use. I hope to
use it also when creating temporary files for input for tools that do
partial conflict resolution. That'll be possible if the function is
more generic. Instead of passing in two contexts (for "other" and
"base") and an optional path (for "local"), let's pass a single list
of files to make backups for. Even if we don't end up using for
partial conflict resolution, this is still a simplification (but I do
have a WIP patch for partial conflict resolution and it is able to
benefit from this).
