[Buildroot] [PATCH] support/download/svn: fix date format for archive creation

[Vincent Fazio]

Previously we would use the date provided by:
`svn info --show-item last-changed-date ...`

The date returned from this command could include sub-second precision
which is not compatible with the PAX options we specify to GNU tar.

Now the returned date is massaged to drop the sub-seconds.
