Fix regtest scheme-engraver.ly wrt to guile-2.2 (issue 322720043 by address@hidden)

Message:
Please review.
Instead of simply replacing 1 by (current-error-port) a variable for the
port could have been used probably.
Opinions?

Description:
Fix regtest scheme-engraver.ly wrt to guile-2.2

Passing a number to format as the port is deprecated in guile-2.2
Thus using (current-error-port) instead
