Once we enable -Wall for BPF sources, compiler will complain about lots
of unused variables, variables that are set but never read, etc.
Fix all these issues first before enabling -Wall in Makefile.

Some of the tests are using x86_64 ABI-specific syscall entry points
(such as __x64_sys_nanosleep and __x64_sys_getpgid). Update them to use
architecture-dependent syscall entry names.
Also update fexit_sleep test to not use BPF_PROG() so that it is clear
that the syscall parameters aren't being accessed in the bpf prog.
Note that none of the bpf progs in these tests are actually accessing
any of the syscall parameters. The only exception is perfbuf_bench, which
passes on the bpf prog context into bpf_perf_event_output() as a pointer
to pt_regs, but that looks to be mostly ignored.

Replace hardcoded 4096 with runtime value in the userspace part of
the test and set bpf table sizes dynamically according to the value.
Do not switch to ASSERT macros, keep CHECK, for consistency with the
rest of the test. Can be a separate cleanup patch.

Both singleton BPF ringbuf and BPF ringbuf with map-in-map use cases are tested.
Also reserve+submit/discards and output variants of API are validated.
