[Wien] expand script name clash with the GNU coreutils utility expand

[Pavel Ondračka]

Dear Wien2k mailing list,

this is not a bugreport per se but it might be wise to remove the short
"expand" symlink to the expand_lapw script from the Wien2k package.

There is actually a name clash with the "expand" utility from GNU
coreutils (
https://www.gnu.org/software/coreutils/manual/html_node/expand-invocation.html#expand-invocation
, installed by default on any linux box). Most users are be probably
unaffected as it is not that widely used but it has some uses (in my
case I was compiling the latest glibc and the build script uses it for
some text processing).

Best regards
Pavel
