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.

utils.bbclass: ensure $0 is correct in wrapper scripts

Some packages (eg mesa) will invoke a tool with --version and do string matches
on the output (i.e. mesa does $LEX --version |grep "^flex ").  This doesn't work
with the combination of wrapper scripts and binaries that use $0 as they output
"flex.real".

Luckily bash's exec lets you set $0.  As we want to use this we can't use env,
but using export appears to work just as well.
