gnu: Make 'mount' interface in static Guile consistent with Guix API.

Browse source 
Rather than expecting a pointer, the version of 'mount' in
guile-static-stripped now takes a string for the 'options' argument, just like
the 'mount' procedure in (guix build syscalls).

* gnu/packages/patches/guile-linux-syscalls.patch (mount): Expect a string or
  #f for 'options' argument.
* gnu/build/file-systems.scm (mount-file-system): Use new 'mount' interface.
