xkb: Silence a warning from gcc 11
I get this:
In function ‘TryCopyStr’,
inlined from ‘CopyISOLockArgs’ at ../xkb/xkbtext.c:875:9:
../xkb/xkbtext.c:720:13: warning: ‘tbuf’ may be used uninitialized [-Wmaybe-uninitialized]
720 | strcat(to, from);
| ^~~~~~~~~~~~~~~~
../xkb/xkbtext.c: In function ‘CopyISOLockArgs’:
<built-in>: note: by argument 1 of type ‘const char *’ to ‘__builtin_strlen’ declared here
../xkb/xkbtext.c:871:10: note: ‘tbuf’ declared here
871 | char tbuf[64];
| ^~~~
Just initialize tbuf so it definitely works.
