Fix PIO error in CICE

Time stamp in components/cice/src/drivers/cpl/ice_history_write.F90
was not synchronized across processors. This can lead to PIO error
"File header is inconsistent among processes" on occasions.
This PR broadcast the time stamp from masterproc to other processors
to fix the issue. (issue #952)

Fixes #952
Fixes #1198
