services/mgmt/device/impl/profile.go: use linux-386 rather than linux-x86

Change the profile name used for 32-bit x86 binaries to be linux-386 rather
than linux-x86 to be consistent with GOARCH=386 (which puts binaries in
bin/linux_386). The earlier discrepancy made it painful to use device publish
to push binaries.
