Patches for inclusion in distributions

[kpcyrd]

hi!

I uploaded androidqf-1.8.1-1-x86_64.pkg.tar.zst to Arch Linux. :) I have the following patch to replace the adb binary in this git repository with /usr/bin/adb, and read the agent binaries from /usr/lib/androidqf/android-collector/collector_*:

Before starting the build I run rm -r assets/ to get rid of the pre-built binaries, so I needed to make sure no Go files from that directory are used.

I also noticed, when running /usr/bin/androidqf it tries to write it's results to /usr/bin/..., which fails unless you run it as root (but even then it's probably not what should be happening), so I applied this patch as well:

 	}

I'm posting this in an issue instead of a pull-request because those changes can't be applied as-is, as they would break the non-distribution use of the binary.

These patches are to be considered MVT-1.1 regardless of course.

Thanks for maintaining a package. I appreciate it!
I opened #80 for the second patch. We can just change this behaviour.
For the first patch I am unsure how to go about this though. We could check if adb is in path and use the system wide version and only fallback to the bundled one if it does not exist. But the bundled version might be newer than the system wide one.
For collector we could do something similar but I dont want to maintain a list of paths where collector is stored in every distro.
Anny suggestions?

[besendorf]

we check a env var with the path of collector. If it is set then we use that and when it's not we use the bundled version. That way package maintainers set the path of collector and we dont need to care where its located

@kpcyrd any objections to the solution in #81 ? Otherwise I would merge that and close the issue
