Closes#441. Adjust bootimg_analyze code:
* Install mkbootimg (which now provides unpackbootimg) instead of
unpackbootimg. In theory, pmbootstrap should recognize this
automatically, however right now it does not yet handle this case.
* The file names of the extracted files have changed.
* Initial Mozilla Flame packages
* Update dtbtool to use LineageOS upstream
* Use mkbootimg --dt flag only when deviceinfo_bootimg_qcdt is defined
* Update mkbootimg to use LineageOS upstream
* Add sparse image flashing on device-mozilla-flame
* Only support SD card install on Mozilla Flame
* Remove useless profile.sh on mozilla flame
* Package DTBs in /usr/lib/linux-mozilla-flame/
* Build and install modules in linux-mozilla-flame
