Dpkg::Compression::FileHandle: Handle new EOF method paramater

Do not forward the integer parameter passed to the EOF method since
perl 5.12, as the IO::Handle::eof function rejects it.

This problem has been latent because for example Dpkg::Source::Patch
was importing the whole POSIX module, including the EOF constant, which
shadowed the EOF method.
