Fix Count Styling on Personal Data Request Tables Post Status Links

[allendav]

The post status links (at the top of the personal data request tables, e.g. "All (1) | Pending (1) | etc" are not formatted like all of the others through-out wp-admin. Existing status-type links wrap the count in a span tag, i.e. they should be like <span class="count">(2)</span>.

Add .count spans to post status count links on request tables

@azaozz - please accept into 4.9.6

To test:

• Navigate to wp-admin > Tools > Export Personal Data
• Ensure that the count that appears next to each post status is now black and enclosed in a .count span (e.g. All (1) | Pending (1) | etc)
• Repeat for wp-admin > Tools > Remove Personal Data
