checkout: add --ignore-skip-worktree-bits in sparse checkout mode
"git checkout -- <paths>" is usually used to restore all modified
files in <paths>. In sparse checkout mode, this command is overloaded
with another meaning: to add back all files in <paths> that are
excluded by sparse patterns.
As the former makes more sense for day-to-day use. Switch it to the
default and the latter enabled with --ignore-skip-worktree-bits.
While at there, add info/sparse-checkout to gitrepository-layout.txt
