Subject: [PATCH] all: use install(1) to install executables

When the destination file already exists, the current install script
will overwrite it with the new executable.

However, when the existing executable is a symlink or hardlink to
something else, like busybox, this effectively overwrites that something
with the new executable, and thus replaces busybox and all its applets
with the code for either of the three commands.

We fix that by simply calling install(1). install(1) is sufficiently
widespread that we don't bother checking for it, as tis is just a
workaround while waiting for the version bump that will eventually fix
it for good.
