docbook2mdoc: There is no need to ever use the eqn(7) inline syntax

[schwarze@mandoc.bsd.lv]

Log Message:
-----------
There is no need to ever use the eqn(7) inline syntax ($$):
Its purpose it to inline eqn(7) source code in the *input* file.
On the *output* side, equations are inlined by default.
To display them, the .EQ block needs to be wrapped in .Bd.
This patch gets rid of another user of "sv".
