[PATCH] tst-realpath-toolong: Fix hurd build

[Siddhesh Poyarekar <siddhesh@sourceware.org>]

We don't really need a bigger buffer for realpath since it should fail
and return NULL.  In the bug too, the buffer itself is not accessed; it
is in fact left untouched.  Drop the PATH_MAX use and pass a single char
address.
