package/gettext-tiny: bump version to add --template option

Some packages (i.e. rygel) uses the msgfmt tool with its --template
option. However, the current version of gettext-tiny (0.3.1) doesn't
support --template flag and exits giving: "fopen: No such file or
directory".

In upstream gettext-tiny they have added support for --template after
lots of modifications, so it's hard to produce a patch to be applied
against 0.3.1. Therefore, we bump the version to the latest master
branch commit.
