openssh: fix using the original config files in srcdir
Currently, we install our own ssh_config and sshd_config into ${S} in
do_compile_append() task. So when finishing compiling, their .out files
are generated by the original files, rather than by our own files.
In most cases, installing "$(CONFIGFILES)" in Makefile will generate .out
files again, and then installing "install-sysconf", which will install
these two files into $(DESTDIR), thus we get what we expect.
However, when parallel installing, "install-sysconf" may be installed
before "$(CONFIGFILES)" sometimes. In this rare case, the .out files
generated in the first time rather than those in the second time will be
installed into $(DESTDIR), and thus we get an unexpect result.
This patch fixes this bug through transfering the installing of our own
files from do_compile_append() into do_configure_prepend().
