[pkgsrc/trunk]: pkgsrc/pkgtools/pkg_comp Update to version 1.24.

description:
Update to version 1.24.

When installing libkver, as required when NETBSD_RELEASE is set
in a pkg_comp configuration, do so in a special purpose prefix and use
it from there.
This is useful when running a bulk build in the chroot or simply
removing all installed packages in it: the libkver package won't
be removed hence the chroot will still be usable.

Approved by MAINTAINER.
