[hurd] Define _PATH_MOUNTED as "/etc/mtab"

From: Justus Winter <[email protected]>

Change the definition of _PATH_MOUNTED to "/etc/mtab". This is the
value used on Linux, and BSD also uses /etc/mtab.

The change is motivated by the fact that on Debian /etc/mtab is a
symbolic link to /proc/mounts. This patch adjusts the macro for
non-linux systems such as Hurd. Changing this using
sysdeps/mach/hurd/paths.h causes build problems because
/usr/include/hurd/paths.h is shadowed by this file. This change is
proposed in the hope that aligning the non-linux targets with the
glibc for Linux is perceived as a good thing while fixing this problem
on Debian/Hurd along the way.
