ftrace: Build trace_btf.c when CONFIG_DEBUG_INFO_BTF is enabled
The trace_btf.c file provides BTF helper functions used by the ftrace
subsystem. Make the compilation of trace_btf.c solely depend on
CONFIG_DEBUG_INFO_BTF, allowing features like funcgraph-retval to also
utilize these helpers.
Additionally, the redundant dependency on CONFIG_PROBE_EVENTS_BTF_ARGS
is removed, as CONFIG_DEBUG_INFO_BTF already depends on
CONFIG_BPF_SYSCALL.
