Theo Buehler ccb8cf88c8 Unbreak torture_config_make_absolute() on OpenBSD ...

The torture_config_make_absolute() and its _no_sshdir() version both
segfault on OpenBSD. The reason for this is that the storage returned
by getpwuid() is backed by mmap and is unapped by the getpwnam() call
in ssh_path_expand_tilde(), so a later access to home segfaults. The
possibility of this happening (getpwnam() overwriting values returned
by getpwuid()) is explicitly called out in POSIX.

A simple fix is to work with copies of username and homedir.
