Marco Vanotti 40fa42bc27 executor/fuchsia: close vmo handle in syz_mmap. 
This commit fixes a handle leak in syz_mmap. The bug was pointed out by
mdempsky during a code review.

The `syz_mmap` function creates a VMO and maps it to a VMAR in the address
specified by the `syz_mmap` parameters. Once a VMO is mapped to a vmar,
the handle to the vmo can be closed without problems.

The new code makes sure that `zx_handle_close(vmo_handle)` gets called before
the `syz_mmap` function returns.
