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. Signed-off-by: Chantry Xavier <shiningxc@gmail.com>
