perf trace: Call bpf__apply_obj_config in 'perf trace'
Without this patch BPF map configuration is not applied.
Command like this:
# ./perf trace --ev bpf-output/no-inherit,name=evt/ \
--ev ./test_bpf_trace.c/map:channel.event=evt/ \
usleep 100000
Load BPF files without error, but since map:channel.event=evt is not
applied, bpf-output event not work.
This patch allows 'perf trace' load and run BPF scripts.
