textproc/aspell-portuguese: Update to version 20070510.0

Due to unicode in one of the PLIST files, the package failed during packaging
due to a libarchive translation error on DragonFly.  Apparently Linux suffers
from this as well.

The last update was 9 years ago.  Updating to current version fixes the
problem for DragonFly.  Linux restriction removed under the assumption that
it also works now.
