libalpm/trans.c : fix a recently introduced breakage in scriptlets handling.

Commit 4853a4aad97fe36f9237ffb7356201adab507a1c used the tmpdir variable
for checking the existence of /bin/sh, without resetting it.

This caused /bin/sh to be deleted during the cleanup part, as soon as a scriptlet
other than pre_upgrade or pre_install was executed.
For example, on the first post_upgrade during a -Su.

I introduced two variables : clean_tmpdir and restore_cwd, for deciding what should
be done in the cleanup part.
