doc/t2h.pm: fix missing CSS with texinfo 6.8 and above

Since texinfo commit 6a5ceab6a48a4f052baad9f3474d741428409fd7, the
formatting functions, in particular begin_file, program_string and
end_file, are prefixed with format_, i.e. format_begin_file, etc.

This patch fixes building the documentation when texinfo 6.8, or
above, is used:

Unknown formatting type begin_file
 at /usr/bin/makeinfo line 415.
Unknown formatting type program_string
 at /usr/bin/makeinfo line 415.
Unknown formatting type end_file
 at /usr/bin/makeinfo line 415.
