Fix for BUG#46591 - .frm file isn't sync'd with sync_frm enabled for

Browse source 
CREATE TABLE...LIKE...
      
The mysql server option 'sync_frm' is ignored when table is created with 
syntax CREATE TABLE .. LIKE.. 
      
Fixed by adding the MY_SYNC flag and calling my_sync() from my_copy() when
the flag is set.

In mysql_create_table(), when the 'sync_frm' is set, MY_SYNC flag is passed 
to my_copy(). 
      
Note: TestCase is not attached and can be tested manually using debugger.
