PR10424: Consider each tracepoint header separately

With the current monolithic tracepoint query module, a failure in any of
the discovered tracepoint headers means that you can't use any of the
others either.  This patch creates a separate query module for each
header so they can pass or fail independently.

* buildrun.cxx (make_tracequery): take a single header name instead of
  globbing for everything we can find.
* hash.cxx (find_tracequery_hash): name the header file we're hashing.
* tapsets.cxx (tracepoint_query::handle_query_func): make sure we don't
  duplicate tracepoints found through different headers.
  (tracepoint_builder::get_tracequery_module): get a header's module
  (tracepoint_builder::init_dw): glob for all tracepoint headers, and
  feed all their modules into dwflpp.
