Add build command to create an apk package from envkernel

Provides a quick way to incrementally compile a kernel and push it to device.

Example usage.

# Compile the kernel:  
$ cd /src/linux/  
$ source /src/pmbootstrap/helpers/envkernel.sh  
$ make tegra_postmarketos_defconfig  
$ make -jX  

# Package kernel and flash to device:  
$ pmbootstrap build --envkernel linux-samsung-p4wifi  
$ pmbootstrap flasher flash_kernel  

# Modify kernel source then incremental compile, package, and flash:  
$ make -jX  
$ pmbootstrap build --envkernel linux-samsung-p4wifi  
$ pmbootstrap flasher flash_kernel

Awesome work @ryang2678! I'll review this within the next week. Rebased on master for now, so it doesn't fail at the flake8 checks anymore, thanks to your other patch

As always your patches have excellent quality and most of my points are nitpicks. It's great that you have added test cases and refactored the APKBUILD file reading. And of course this is a super useful feature in general.

Keep up that amazing stuff @ryang2678

resolved all discussions

By Oliver Smith on 2019-02-15T15:25:37

(envkernel.sh did not mention "run-script" in the list of aliases output, I've added it there.)

I've linked to this MR in the wiki: https://wiki.postmarketos.org/wiki/Mainlining_Guide#envkernel.sh

envkernel.sh supports quite a few features now, especially with the complete workflow you have described here. I think it deserves its own wiki page, in case somebody wants to start it. (Otherwise, the references to the advanced features are linked, so it's good enough for now.)

Tested and working both the pmbootstrap command, as well as run-script, and it is working as expected. Thanks again @ryang2678!

Awesome work! I've linked to it from the mainlining guide, and removed the "see also" part to the new page.
