[Buildroot] [git commit] support/dependencies: require tar >= 1.35

[Arnout Vandecappelle]

commit: https://git.buildroot.net/buildroot/commit/?id=b11956fb6690e0083eab9f30b5dc146fc40c2d5f
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

We can't stay in the past forever and ever...

Since tar 1.35, the way some fields (devmajor and devminor) are stored
has changed. These fields exist for each file in the tarball, but only
used for device nodes. In previous versions of GNU tar, they were set to
zero; since 1.35, they are set to empty.

Although this doesn't change anything about the content of the tarball,
and it will be extracted in exactly the same way regardless of the tar
version used for extracting, it does change the hash of the tarball.
Therefore, we have to
- make sure that the correct version of tar is used;
- update the format version so that the filename is different from
  before.

Increment all BR_FMT_VERSION by one.

Require tar >= 1.35 instead of < 1.35.
