injection_points: Enable entry count in its variable-sized stats
This serves as coverage for the tracking of entry count added by
7bd2975fa92b as built-in variable-sized stats kinds have no need for it,
at least not yet.
A new function, called injection_points_stats_count(), is added to the
module. It is able to return the number of entries. This has been
useful when doing some benchmarking to check the sanity of the counts.
