Fix in gen_task1_data.sh from CHiME7

[boeddeker]

I got the error:

local/gen_task1_data.sh: line 36: [-d: command not found

and PyCharm complained:

Couldn't parse this test expression. Fix to allow more checks.
See SC1073.
You need a space after the [ and before the ].
See SC1035.

I think someone forgot to add whitespaces, otherwise it is not valid bash code.

@popcornell, is it already considered in your PR, or should I merge it?

[popcornell]

You should merge it. Somehow I did not get this error on my side, and I like rerun this bit like 10 times.
It is indeed wrong but maybe more recent bash versions are able to parse it ?

OK, thanks!
