[3dprinter-general] Bug#1066949: slic3r-prusa: Unneeded build dependencies on xvfb, xauth

[Plasma (David Paul)]

Source: slic3r-prusa
Version: 1.37.1+dfsg2-1
Severity: minor

Dear Maintainer,

Please drop xvfb and xauth from the build dependencies for slic3r-prusa.

Prior to version 1.37.1+dfsg2-1 of slic3r-prusa, the debian/rules file
made use of xvfb (and, by extension, xauth), but this is no longer the
case.

Thanks,
