site/common-linux: coreutils: get the uptime program to work

coreutils configure script needs to know whether /proc/uptime is
available, but this is not possible in a cross-compilation
context. This leads to an uptime program that fails to work on the
target, as it has been compiled without /proc/uptime reading support.

This commit fixes that by telling coreutils at configure time that
/proc/uptime will be available on the target (which seems to be a
reasonable assumption on Linux systems).

This commit is made with great inspiration from Thomas Petazzoni's
patch to buildroot to fix the same issue.
