When libperf is built alone in-source, $(OUTPUT) isn't set. This causes
the generated uapi path to resolve to '/../arch' which results in a
permissions error:

  mkdir: cannot create directory '/../arch': Permission denied

Fix it by removing the preceding '/..' which means that it gets
generated either in the tools/lib/perf part of the tree or the OUTPUT
folder. Some other rules that rely on OUTPUT further refine this
conditionally depending on whether it's an in-source or out-of-source
build, but I don't think we need the extra complexity here. And this
rule is slightly different to others because the header is needed by
both libperf and Perf. This is further complicated by the fact that Perf
always passes O=... to libperf even for in source builds, meaning that
OUTPUT isn't set consistently between projects.

Because we're no longer going one level up to try to generate the file
in the tools/ folder, Perf's include rule needs to descend into libperf.
Also fix the clean rule while we're here.

Therefore we must also generate the syscall header for arm64 before building Perf. Add it as a dependency to libperf which uses one syscall number. Perf uses more, but as libperf is a dependency of Perf it will be generated for both. Future platforms that need this will have to add their own syscall-y targets in libperf manually. Unfortunately the arch specific files that do this (e.g. arch/arm64/include/asm/Kbuild) can't easily be imported into the Perf build. But Perf only needs a subset of the generated files anyway, so redefining them is probably the correct thing to do.

no longer using a generic syscall header and generates one from the

arm64 before building Perf.

Add it as a dependency to libperf which uses one syscall number. Perf
uses more, but as libperf is a dependency of Perf it will be generated
