Hello, I have been experimenting with the new package zchunk. zchunk
comes with a utility zck_gen_zdict, which utilizes the zstd program.
zstd is a propogated input of zck_gen_zdict, but it appears that
zck_gen_zdict hardcodes zstd to /usr/bin:

```
christopher@theoden ~/Scratch$ zck_gen_zdict clonezilla-live-2.6.7-28-
amd64.iso.zck
Unable to find /usr/bin/zstd
Error generating dict
```

My system information:

```
christopher@theoden ~/Scratch$ neofetch --stdout

Fixed with commit 448de3966e:

Toggle snippet (11 lines)
$ zck_gen_zdict netinst.iso.zck
Trying 5 different sets of parameters
k=1998
d=8
f=20
steps=4
split=75
accel=1
Save dictionary of size 112640 into file netinst.iso.zdict

Thanks for the tests!

Closing.
