  rawfbt: prvname is not properly set

The char array prvname[] is set for each provider.  It is used in the
file that implements the provider.  It might also be passed to
dt_sdt_populate() via a function argument.

However, dt_provider_tp.h also defines the macro GROUP_DATA in terms of
prvname.  In turn, GROUP_DATA is used not only in dt_prov_dtrace.c but
then again in dt_prov_fbt.c to define FBT_GROUP_DATA.

In commit 0b7c5a632 ("fbt, rawfbt: consolidate code to avoid duplication"),
the fbt and rawfbt providers are combined into a single file.  Thus, two
uses of prvname collide.  The in-file collisions get resolved, but the
cascade of macro definitions does not:  FBT_GROUP_DATA ends up using
"fbt" for both fbt and rawfbt providers.  As a result, it is possible
for rawfbt probes not to be seen.

Notice that GROUP_DATA is always paired with prp->desc->prb.  Therefore,
simply replace:
    -#define GROUP_DATA     getpid(), prvname
    +#define PROBE_DATA     getpid(), prp->desc->prv, prp->desc->prb
This makes the code more compact and relieves the macro definitions from
needing prvname.  It also makes the FBT_GROUP_DATA macro unnecessary.

The format (FMT) macro is similarly renamed and redefined to include the
probe info.

Add a test to check that a rawfbt probe can be found behind an fbt probe
when the probe description has a wildcard provider.
