tree.sh: Delete files *before* updating hashes

The current logic deletes old project files e.g. sources,
but *after* updating the project hash.

This means that if a deletion fails, and the directory
is still there (e.g. src/coreboot/default/) afterward, it's
now a tainted archive, yet the hash has been updated, so
subsequent runs of the build system will cause unknown
errors.

This patch fixes that, by first copying the new hash to
a temporary file. *Then*, deletions are handled, and the
final hash file is updated afterward.

The code is now a bit more bloated as a result, but this will
reduce the risk of tainted sources being handled under fault
conditions.
