Install script fails on Synology systems due to lack of unzip command

[Webreaper]

The new install script for rclone fails on a Synology OS because Synology doesn't have the unzip command by default. Instead, Synology provides the 7z command.

So if we replace the existing unzip command:

unzip -a $rclone_zip -d $unzip_dir
with this:

if hash unzip 2>/dev/null; then
	unzip -a $rclone_zip -d $unzip_dir 
else
	7z x $rclone_zip -o$unzip_dir
fi

the script will work on Synology.

@qaskai what do you think about making the script look for 7z if unzip isn't available?

it would be quite nice if the script errored at the start if neither is available as unzip isn't a standard install for eg, debian.

Yeah, that’s a good idea. Now I wonder how I could fail to consider this problem while making the script! I’ll make a PR ASAP.

Also apologies to @Webreaper for the slow response.

Don't fret, it's really no biggie. Having a script at all is great! Thanks!

I've pushed up a new script to rclone.org which should work for you now - thanks to @qaskai for the changed :-)
