Return EEXIST when overwritting a file as long as the caller has exec
permission on the parent directory, even if the caller doesn't have
write permission.
Also reordered the mount write check, which happens before permission
is checked.
Closes#5164

- BindSocketThenOpen test was expecting the incorrect error when opening
a socket. Fixed that.
- VirtualFilesystem.BindEndpointAt should not require pop.Path.Begin.Ok()
because the filesystem implementations do not need to walk to the parent
dentry. This check also exists for MknodAt, MkdirAt, RmdirAt, SymlinkAt and
UnlinkAt but those filesystem implementations also need to walk to the parent
denty. So that check is valid. Added some syscall tests to test this.
