indexcap.py: fix tmpdir handling, python 3 compat

Add Python 3 compatibility to indexcap.py and only create a tmpdir for
actions that need it. Only remove tmpdir for the compare action and
try to remove the temp dir even if an exception occurs.

In list_protos_in_cap.sh, rename BIN_DIR to WS_BIN_PATH (matching
test/config.sh) and allow it to be overridden from the environment.

Tested with Python 2.6.6, 2.7.9, 3.2.6, 3.4.3 as follows (with tshark
built using cmake and '-b /tmp/wsbuild/run'):

    tools/indexcap.py out pop-ssl.pcapng;
    tools/indexcap.py out pop-ssl.pcapng --list-all-proto;
    tools/indexcap.py out pop-ssl.pcapng --list-all-files;
    tools/indexcap.py out pop-ssl.pcapng --list-all-proto-files=ssl;
    rm out;

Python 2.5.6 does not work (there is no multiprocessing module). The
dict output in Python 3.4.3 is different (has the hash function
changed?)
