ppp: mppe: Add softdep to arc4

[ Upstream commit aad1dcc4f011ea409850e040363dff1e59aa4175 ]

The arc4 crypto is mandatory at ppp_mppe probe time, so let's put a
softdep line, so that the corresponding module gets prepared
gracefully.  Without this, a simple inclusion to initrd via dracut
failed due to the missing dependency, for example.
