Drop unzip if bsdunzip exists

[oech3]

engrampa 1.28.2-2 of Arch Linux depends on unzip and libarchive.
However, libarchive has bsdunzip, and unzip is not actively developed.
Would you drop unzip?

Is this a drop-in replacment with identical usage and syntax?

[oech3]

No. maybe subset. Password unlock is lacking at least for.
Encoding support with -O exists.

I will leave this for other team members to work on. I've little experience with this part of the code and am rather task-saturated with the mess in my country right now
