tree.sh: Place target builds under tree/target/

as opposed to target/

for example:

image the command:

./mk -b u-boot amd64coreboot

This would put the U-Boot binaries here:
elf/u-boot/amd64coreboot/default/

With this change, they now go here:

elf/u-boot/x86_64/amd64coreboot/default/

This solves a problem that existed previously, where
you could modify a given tree in a multi-tree project,
but cached builds for targets branching separately off
of each tree would not be deleted, and thus not re-built.

This accomplishes such a result, without needing to
further check hashes of individual targets.

The latter will still be done, in a future change, because
this change doesn't fix another problem:

If you change a given config, e.g. targetname "foo" which
uses tree "bar", elf/foo/ would not be removed automatically
for re-build.

So this change only deletes individual target builds when
their master tree changes.

Where the target and tree are the same, this also means
elf/tree/target/

for example: seabios/default would create binaries in:

elf/seabios/default/default/

not:

elf/seabios/default/
