samples/bpf: syscall_tp_user: Fix array out-of-bound access
[ Upstream commit 9220c3ef6fefbf18f24aeedb1142a642b3de0596 ]

samples/bpf: syscall_tp_user: Fix array out-of-bound access
[ Upstream commit 9220c3ef6fefbf18f24aeedb1142a642b3de0596 ]
Commit 06744f24696e ("samples/bpf: Add openat2() enter/exit tracepoint to syscall_tp sample") added two more eBPF programs to support the openat2() syscall. However, it did not increase the size of the array that holds the corresponding bpf_links. This leads to an out-of-bound access on that array in the bpf_object__for_each_program loop and could corrupt other variables on the stack. On our testing QEMU, it corrupts the map1_fds array and causes the sample to fail:
# ./syscall_tp prog #0: map ids 4 5 verify map:4 val: 5 map_lookup failed: Bad file descriptor
Dynamically allocate the array based on the number of programs reported by libbpf to prevent similar inconsistencies in the future

We have switched to memcg-based memory accouting and thus the rlimit is not needed any more. LIBBPF_STRICT_AUTO_RLIMIT_MEMLOCK was introduced in libbpf for backward compatibility, so we can use it instead now.
This patch also removes the useless header sys/resource.h from many files in samples/bpf.

For the problem of increasing fragmentation of the bpf loader programs, instead of using bpf_loader.o, which is used in samples/bpf, this commit refactors the existing tracepoint tracing programs with libbbpf bpf loader.
- Adding a tracepoint event and attaching a bpf program to it was done through bpf_program_attach(). - Instead of using the existing BPF MAP definition, MAP definition has been refactored with the new BTF-defined MAP format.

Most samples don't actually need the local libbpf.h they simply include it to get to bpf/bpf.h. Include bpf/bpf.h directly instead.
