bpf/preload: Clean up .gitignore and "clean-files" target kernel/bpf/preload/Makefile was recently updated to have it install libbpf's headers locally instead of pulling them from tools/lib/bpf. But two items still need to be addressed. First, the local .gitignore file was not adjusted to ignore the files generated in the new kernel/bpf/preload/libbpf output directory. Second, the "clean-files" target is now incorrect. The old artefacts names were not removed from the target, while the new ones were added incorrectly. This is because "clean-files" expects names relative to $(obj), but we passed the absolute path instead. This results in the output and header-destination directories for libbpf (and their contents) not being removed from kernel/bpf/preload on "make clean" from the root of the repository. This commit fixes both issues. Note that $(userprogs) needs not be added to "clean-files", because the cleaning infrastructure already accounts for it. Cleaning the files properly also prevents make from printing the following message, for builds coming after a "make clean": "make[4]: Nothing to be done for 'install_headers'." v2: Simplify the "clean-files" target.

bpf/preload: Make sure Makefile cleans up after itself, and add .gitignore The Makefile in bpf/preload builds a local copy of libbpf, but does not properly clean up after itself. This can lead to subsequent compilation failures, since the feature detection cache is kept around which can lead subsequent detection to fail. Fix this by properly setting clean-files, and while we're at it, also add a .gitignore for the directory to ignore the build artifacts.
