python-smartpm: add gettext-native to DEPENDS

Fixes the following failure at do_install building python-smartpm-native if gettext-native has not already been built and gettext tools are not installed on the host:

| compiling locale/it/LC_MESSAGES/smart.po -> locale/it/LC_MESSAGES/smart.mo | sh: msgfmt: command not found
...
| creating $D/usr/share/share/locale/it/LC_MESSAGES
| error: can't copy 'locale/it/LC_MESSAGES/smart.mo': doesn't exist or not a regular file

Note that we need gettext-native in DEPENDS and not "inherit gettext" here because for native variants, gettext.bbclass instead adds gettext-minimal-native to DEPENDS and that does not provide the msgfmt command.
