Bug#1017920: sysfsutils: please make the build reproducible

[Chris Lamb]

Source: sysfsutils
Version: 2.1.1-2
Severity: wishlist

Hi,

Whilst working on the Reproducible Builds effort [0] we noticed that
sysfsutils could not be built reproducibly.

This is because the call to date(1) was missing the -u/--utc flag,
so that the manpage date based on the value of SOURCE_DATE_EPOCH
would vary depending on the host system's timezone setting.

Patch attached that appends -u to the pod2man call.
