plugins/hwprofile: adapt to the new plugin arguments scheme

Parsing boolean arguments correctly (e.g. pattern=on or source=false).
Introduced a new "track" argument that takes a [read|write] value. This
substitutes passing read or write to "arg=" that is deprecated.

Also, matches are now taken one by one through the "match" argument.

 The hwprofile tool can only be used with system emulation and allows
 the user to see what hardware is accessed how often. It has a number of options:
 
- * arg=read or arg=write
+ * track=read or track=write
 
  By default the plugin tracks both reads and writes. You can use one
  of these options to limit the tracking to just one class of accesses.
