prog: generate choice table only for enabled calls
We used to generate a choice table and do its normalization for all
present syscalls, also it was not considered during the /prio page
generation.
Enabled/disabled syscalls were accounted for in the choice table
construction, but there's a chance that the resulting table was still
somewhat skewed.
The situation must have become worse after several thousands of auto
syscalls were added.
