Store autopkgtest flag in sources

Extend read_sources to store a new AUTOPKGTEST boolean flag, which is true if
the Testsuite: field exists and starts with "autopkgtest" (this covers autodep8
cases like autopkgtest-pkg-perl).

Extend TestData.add() to take a new testsuite argument which specifies the
source's Testsuite: field.
