usr.sbin: normalize paths using SRCTOP-relative paths or :H when possible

This simplifies make logic/output

Fix build after r314656

Some of the changes I introduced to use .ALLSRC were correct in spirit,
but incorrect in reality -- in particular, ../Makefile.inc hadn't been
pulled in via bsd.init.mk (via bsd.lib.mk, bsd.prog.mk), so the value
of .ALLSRC (evaluated immediately) was empty. .include bsd.init.mk
explicitly so we can be certain that the values used as dependencies in
the targets are defined when the target recipe has been evaluated.

Reminder: thou shalt separate out separate functional changes before
committing them.

Fix type mismatches for malloc(3) and Co.

This is rather pedantic, as for most architectures it holds that
sizeof(type *) == sizeof(type **)
