android-tools: drop GPL-2.0-only from LICENSE

The GPL-2.0 entry dates back to the first recipe (AOSP android-5.1.1_r37,
2016) and was carried over unchanged to the Debian android-platform-tools
based 35.0.2 recipe.

In the android-5.1.1_r37 repos the recipe fetched, the only GPLv2 mentions
are headers which are dual licensed "Apache 2.0 OR GPLv2"
(system/core include/cutils/ashmem.h, include/utils/ashmem.h,
include/log/logger.h), kernel headers in libion which are not built, and
documentation templates. Apache-2.0 can be chosen for all of them.

The 35.0.2 sources come from Debian's android-platform-tools, whose
debian/copyright lists no GPL license: the files are Apache-2.0, BSD,
Expat, Khronos, PSF and public-domain, and a scan of the unpacked tarball
finds no GPL licensed source files.

Remove GPL-2.0-only from LICENSE and LIC_FILES_CHKSUM so that the recipe is
not wrongly treated as GPL by license based tooling (e.g. copyleft source
archiving).
