tests: Speed up tshark operations

Hide /usr/share/wireshark from hostfs to prevent tshark from loading all
the data from there since that can take significant amount of time and
is not really needed for the test cases. In addition, set HOME to point
to local tmpfs to avoid unnecessary references through hostfs.
