share: stop using 'islocal' with repo instance

Having this level of polymorphism of the `islocal` function is weird, and we
already have a way to know if the repo is local from the object itself.

We are about to deprecate passing a non-bytes object to `islocal`, so clean this
up beforehand.

We might want to clean up this function too in the future, however this is
another adventure.

  $ hg init

  $ echo 123 > a
  $ hg add a
  $ hg commit -m "first" a

  $ mkdir sub
  $ echo 321 > sub/b
  $ hg add sub/b
  $ hg commit -m "second" sub/b

  $ cat sub/b
  321

  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ cat sub/b 2>/dev/null || echo "sub/b not present"
  sub/b not present

  $ test -d sub || echo "sub not present"
  sub not present
