redhat/spec: Update bpftool versioning scheme
The upstream has changed the versioning scheme of bpftool [1].
Instead of following the kernel version, it is now deduced from the
libbpf version by adding +6 to the libbpf major version number.
This appropriately updates the bpftool sub-package version number. The
version is deduced automatically from the libbpf version, which can be
retrieved from tools/lib/bpf/libbpf.map.
One problem is that even though RPM allows to override sub-package
version, doing that overrides the internal %{version} macro. The macro
is used later throughout the specfile, so we reset it to its default
value (%{specversion}) at the end of the bpftool sub-package definition.
