Update misc/py-anita to 1.40.  Changes from 1.39:

Work around a bug in the urllib library of Python 2.7.12 that causes
FTP transfers to fail with the error message "[Errno ftp error] 200
Type set to I"; see https://bugs.python.org/issue27973.

When halting the child results in an EOF, don't print the exception
since that may be confused with a failure.

Run vmstat -s at the end of the ATF tests to help diagnose issues
like excessive paging due to insufficient memory.

Increase the default of the --test-timeout option from 3 hours to 8
hours, since the sparc tests are now taking more than 5 hours.

Increase the default disk size to 1526M, as 1G is no longer enough
for amd64.

Pass format=raw in the qemu -drive option to suppress warnings in
recent qemu versions.
