Use default ignore rules for source package with format >> 1.0

* scripts/dpkg-source.pl: Remove default ignore patterns
and move them...
* scripts/Dpkg/Source/Package.pm: ...here. The init_options()
method now will give default values to the corresponding
options.
* scripts/Dpkg/Source/Package/V2_0.pm (init_options): Call
the parent init_options() to get the default ignore rules.
* scripts/Dpkg/Source/Package/V1_0.pm: Don't call the
parent init_options() as we don't want default values
for format 1.0.
