Subject: [PATCH] tools/vm: Add missing Makefile rules

Currently the tools/vm Makefile has a rather arbitrary implicit build
rule; page-types is the first value in TARGETS so lets just build that
one! Additionally there is no install rule and this is needed for
make -C tools vm_install to work properly.

Provide a more sensible implicit build rule and a new install rule.

Note that the variables names used by the install rule (DESTDIR and
sbindir) are copied from prior-art in tools/power/cpupower.
