Ludovic Courtès e05f7c55d7 file-systems: Open files with O_CLOEXEC.
Since this code is run from PID 1, this ensures file descriptors to
sensitive files and devices are not accidentally leaked to
sub-processes.

* gnu/build/file-systems.scm (call-with-input-file): New procedure.
(mount-file-system): Use 'close-fdes' + 'open-fdes'.
