tools/libxc, tools/libelf: Relicense under LGPL v2.1

Relicense these two libraries under LGPL v2.1 only except where
individual files already included the "or later" provision.

Copyright holders have been contacted by Stephen Spector and have all
agreed this change.

Removed tools/libxc/ia64/aclinux.h since it appeared to be
unused. There is a separate, more up to date, copy in
xen/include/acpi/platform/aclinux.h which does appear to be used.

Clarify the license of MiniOS privcmd.h under the same terms as other
tools/include/xen-sys headers.
