Move DEV_MAPPER_PATH from DMRaid.h to Utils.h (#760080)

Browse source 
Renamed from DEV_MAP_PATH to DEV_MAPPER_PATH.  Moved so that the
constant is logically intended for use outside of the DMRaid class.

Also specifically make the string constant have external linkage, rather
than the default internal (static) linkage for constants, so that there
is only one copy of the variable in the program, rather than one copy in
each compilation unit which included DMRaid.h.  Namely DMRaid.cc and
GParted_Core.cc.
