Cygwin fork() fails in NtCreateSymbolicLinkObject(). We successfully
create the link but then fail to alloc_handle() with STATUS_ACCESS_DENIED,
because the requested access rights exceed what the owner is allowed.
Allow it more.

Thank you to Dmitry Timoshkov for debugging the security details from
alloc_handle() onwards.
