nim-gdb is missing from all released packages

[genotrance]

File is present in Nim repo but not in released xz or zip files.

Ouch.

[genotrance]

tools/nim-gdb.py is present whereas bin/nim-gdb is missing. Sorry, I should have been more accurate.

@Araq As the author mentioned, the fix is not complete... There's no nim-gdb executable shell script in the bin folder.

Notice how the timestamp is different as I need to copy and create nim-gdb myself:

I hit on this bug today with Nim 1.2.0.
