[OE-core] [OE-Core][PATCH v2] iputils: Set prefix correctly for usrmerge

[Alex Kiernan]

Fix build with usrmerge enabled:

  WARNING: iputils-s20190709-r0 do_package: iputils: alternative target (/usr/bin/ping or /usr/bin/ping.iputils) does not exist, skipping...
  WARNING: iputils-s20190709-r0 do_package: iputils: NOT adding alternative provide /usr/bin/ping: /usr/bin/ping.iputils does not exist

Changes in v2:
- use root_prefix, not prefix, so non-usrmerge case installs into /bin (and friends)
