mail: Add mail- prefix to mail cli utilities

Rename mail utility programs (yet again), to be prefixed with `mail-`
instead of `neomutt-`. Also did not substitute with other MUA like
`aerc-` since these utilities are mostly independent of specific
implementations.

The very specific `neomutt-filer` implementation script I completely
removed since for aerc the same can be achieved with a simple
configuration option.
