chore(deps): update tar to 0.4.42

The new version of tar enables the creation of sparse tar archives by
default.  The ability to read such sparse entries was added in tar
0.4.6, which has been in use starting from Cargo 0.13 and Rust 1.12.
Additionally, `docker cp` doesn't support sparse tar entries in the GNU
format.  For compatibility with older versions of Rust and Cargo, as
well as with `docker cp`, this commit disables sparse archive creation
in the corresponding cases where the `tar::Builder` is used.  See
#14594.
