spec_linux.go: Rename IDMapping fields to follow syscall.SysProcIDMap 

'From' and 'To' are potentially ambiguous for a one-to-one map like
this, and there's already an established name convention in
SysProcIDMap [1].  This commit removes the mental overhead of two
separate naming schemes for the same information.  I'd like to drop
IDMapping entirely in favor of SysProcIDMap, but SysProcIDMap doesn't
give the JSON hints we need for (de)serializing.
