gpgv: Flush the files before checking for errors
This is a follow up to the previous issue where we did not check if getline() returned -1 due to an end of file or due to an error like memory allocation, treating both as end of file. Here we ensure that we also handle buffered writes correctly by flushing the files before checking for any errors in our error stack. Buffered writes themselves were introduced in 1.1.9, but the function was never called with a buffered file from inside apt until commit 46c4043d741cb2c1d54e7f5bfaa234f1b7580f6c which was first released with apt 1.2.10. The function is public, though, so fixing this is a good idea anyway. Affected: >= 1.1.9
