Install BIND with "make DESTDIR=<PATH> install"

BIND installation should be done by setting DESTDIR during "make
install" not by setting prefix via ./configure.

Make sure that installation with DESTDIR=<PATH> works by checking that
it installed the named binary and it's respective man page to a
well-known place.

Also rename install path variable from BIND_INSTALL_PATH to
INSTALL_PATH to avoid namespace clash in stress tests which use
BIND_INSTALL_PATH variable to configure path to BIND9 binaries.
