selftests/bpf: Use "__se_" prefix on architectures without syscall wrapper
[ Upstream commit 046b841ea7c528931e7d2e74d5e668aa6c94c1fc ]
On architectures that don't use a syscall wrapper, sys_* function names
are set as an alias of __se_sys_* functions. Due to this, there is no
BTF associated with sys_* function names. This results in some of the
test progs failing to load. Set the SYS_PREFIX to "__se_" to fix this
issue.
