[Reproducible-builds] Bug#815248: liblcms2: Writes uninitialized strings when writing named colors

Package: liblcms2
Version: 2.6-3

Hi!

When writing named colors, liblcms2 currently writes uninitialized memory
when the prefix, suffix, or root color name strings are not
32-characters long (including the NULL terminator). This prevents colord
from building reproducibly.

The attached patch will zero the memory before copying the profile
strings to ensure a consistent output.
