drop! ci: run win+VS jobs on forks too

The `vs-build` job (and transitively the `vs-test` matrix, which
declares `needs: [ci-config, vs-build]`) is gated on
`github.event.repository.owner.login == 'git-for-windows'`, so a
push to any other fork skips both.  That means t7508 msysgit#126 ("status
does not re-read unchanged 4 or 8 GiB file"), which only stresses
the MSVC-only `ftruncate -> _chsize` compat shim, has no CI
coverage when this topic is verified from a personal fork.

Drop the owner check so the MSVC build runs here too.  This commit
is intentionally a no-op for `git-for-windows/git` itself; it only
unblocks fork verification.

Drop this commit before squashing the topic for upstream
submission; upstream Git has no `vs-test` job and the gate is
specific to the Git for Windows fork's CI matrix.
