Bug 20922: Remove use of Koha::Number::Price in updatedatabase.pl

Bug 20922: Remove use of Koha::Number::Price in updatedatabase.pl

Koha::Number::Format->round use Number::Format->round with a precision=2
We should use it directly instead of Koha::* modules. It will avoid the
DB entry to fail because schema changes.

Basically, the update code uses Koha::Number::Price, which in full
modern object mode goes for its newly added *p_sep_by_space* _in the
18.05 code_.  But the DB doesn't have it yet (it comes with 17.12.00.022).
