dlt-logd-converter: fixes android 12 compilation (#445)

* Since android 12 release (and the introduction of this commit
https://chromium.googlesource.com/aosp/platform/system/
logging/+/b674866203f05957b2ac5db94c3c0fe3d1d36793), the define
ANDROID_LOG_RDONLY and friends have been removed (see the commit
for the explanation). Therefore, dlt-logd-converter can't compile
anymore since this version.
* ANDROID_LOG_RDONLY was a define on O_RDONLY. O_RDONLY is now used
to allow the compilation on android 12 as well as previous versions
* <log/logprint.h> include is removed because we aren't using any
API from this file and moreover, this file shouldn't be included from
vendor application (not part of public API)
* Direct include on "system/core/include" inside Android.bp is removed
because it was previously used to find <log/logprint.h>. This should
be avoided. We should keep android build system providing right
headers path for us :)
