lint: Adjust patch file length check.

With the switch to "ustar" format in commit
bdf5c16ac0, the maximum file length has
increased.

* guix/lint.scm (check-patch-file-names): Adjust margin used to check for
  patch file lengths. Increase allowable patch file length appropriate to new
  tar format. Extend warning to explain that long files may break 'make dist'.
* tests/lint.scm: Update tests accordingly.
