Antonio Russo 5371d8dae7 ZTS: close in mmapwrite.c
commit a7304ab9c1 upstream

mmapwrite is used during the ZTS to identify issues with mmap-ed files.
This helper program exercises this pathway by continuously writing to a
file.  ee6bf97c7 modified the writing threads to terminate after a set
amount of total data is written.  This change allows standard program
execution to reach the end of a writer thread without closing the file
descriptor, introducing a resource "leak."

This patch appeases resource leak analyses by close()-ing the file at
the end of the thread.
