Bump tar 1.30

Bump: tar -> 1.30 gzip -> 1.9 xz-utils -> 5.2.4

Thank you for your contribution. Some notes:

• tar build does not depend on bzip2, gzip and xz-utils, so we don't need to stage them when building tar. The binaries from bzip2, gzip and xz-utils packages are invoked by tar at runtime instead.
• Those share/info/dir remove commands where there to avoid situations where different packages had this file, thus needing -force-overwrite install flag to co-exist. We didn't remove man pages and docs before. I don't see much point in removing them: the increase in size is neglectable I think.
• I don't see why you removed --disable-nls configure flag for gzip. Could you explain this change?

* `tar` build does not depend on `bzip2`, `gzip` and `xz-utils`, so we don't need to stage them when building `tar`. The binaries from `bzip2`, `gzip` and `xz-utils` packages are invoked by `tar` at runtime instead.

My bad. Fixed;

* Those `share/info/dir` remove commands where there to avoid situations where different packages had this file, thus needing `-force-overwrite` install flag to co-exist. We didn't remove `man` pages and docs before. I don't see much point in removing them: the increase in size is neglectable I think.

Following the conventions... :) Reverted;

--disable-nls is unknown option for gzip configuration script, however, it is harmless... Reverted;
