Fix a file descriptor leak in mod_include. When we include a

file, we use a sub-request, but we didn't destroy the sub-request
immediately, instead we waited until the original request was
done.  This patch closes the sub-request as soon as the data is
done being generated.

This passes all tests in the test suite.
