libbpf: Fix syscall access arguments on riscv
[ Upstream commit 8a412c5c1cd6cc6c55e8b9b84fbb789fc395fe78 ]
Since commit 08d0ce30e0e4 ("riscv: Implement syscall wrappers"), riscv selects ARCH_HAS_SYSCALL_WRAPPER so let's use the generic implementation of PT_REGS_SYSCALL_REGS().

libbpf: Use local includes inside the library
In our monrepo, we try to minimize special processing when importing (aka vendor) third-party source code. Ideally, we try to import directly from the repositories with the code without changing it, we try to stick to the source code dependency instead of the artifact dependency. In the current situation, a patch has to be made for libbpf to fix the includes in bpf headers so that they work directly from libbpf/src.

Set up generic support in bpf_tracing.h for up to 7 syscall arguments tracing with BPF_KSYSCALL, which seems to be the limit according to syscall(2) manpage. Also change the way that syscall convention is specified to be more explicit. Subsequent patches will adjust and define proper per-architecture syscall conventions.
__PT_PARM1_SYSCALL_REG through __PT_PARM6_SYSCALL_REG is added temporarily to keep everything working before each architecture has syscall reg tables defined. They will be removed afterwards.
