[PATCH v2] xen: use BOOT_DIR as xen.gz install location

[Olaf Hering <olaf@aepfle.de>]

Xen is currently installed into /boot, which is a hardcoded path. This
makes it impossible to install two xen.rpm packages from 'make rpmball'
in parallel because rpm complains about conflicting files.
Use BOOT_DIR to define the install path to make it possible to install
xen.gz below --prefix=.

v2:
 use BOOT_DIR instead of XEN_BOOT_DIR
 add variable to config/StdGNU.mk instead of xen/Makefile
