Bug#1134666: fonts-spleen: please make the build reproducible

Source: fonts-spleen
Version: 2.2.0-4
Severity: wishlist

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
fonts-spleen could not be built reproducibly.

This is because the invocation of gzip does not pass the "--no-name"
argument, meaning that the existing filename and the original timestamp
are embedded in the file. This means that the build time is ultimately
embedded in the binary .deb:

│ │ │ ├── ./usr/share/consolefonts/spleen-12x24.psfu.gz
│ │ │ │ ├── filetype from file(1)

etc.

Patch attached.
