cups support for print/a2ps (patch incl.)

[iMil <imil%home.imil.net@localhost>]

Hi,

print/a2ps is built using:

CONFIGURE_ENV+= LPR=lpr

which fails when you are using CUPS, as the recommended binary is
${PREFIX}/bin/lpr in such case.

Here comes a simple patch which provides this option, ok for commit ?
