spec: improve page breaks
Fix the almost empty page, that would only have "2.2.1.1 Counter
Storage" and one line of text, the related table starting a new page
(although no explicit page break was there).
Add a page break before "2.2. SIM/USIM Provisioning" to avoid that
almost blank page, and add some more page breaks before big headlines
for consistency and better readability.
