[PATCH 2/4] trace-filter: Remove the Gtk dependency in trace-filter-hash.

["Yordan Karadzhov (VMware)" <y.karadz@gmail.com>]

trace-filter-hash implements a set of hashing tools, used when
filtering the trace data. Removing the Gtk dependency will
simplify the usage of these tools from a user application.
