mdocml: Drop the AUTOINCREMENT PRIMARY KEYs from the mlinks and keys

[schwarze@mdocml.bsd.lv]

Log Message:
-----------
Drop the AUTOINCREMENT PRIMARY KEYs from the mlinks and keys tables.
They are completely unused, and i cannot imagine what they *could*
ever be used for; but apparently, they are expensive to generate.

Standard DB build time goes down by 10%, now at 1.9x of makewhatis.
