This patch append new syntax to BPF object section name to support
probing at uprobe event. Now we can use BPF program like this:

SEC(
"target:/lib64/libc.so.6\n"
"libcwrite=__write"
)
int libcwrite(void *ctx)
{
return 1;
}

Where, in section name of a program, before the main config string,
we can use 'key:value' style options. Now the only option key "target"
is for uprobe probing.

looks good.
why use ':' separator? '=' should work as well and will be more
consistent ?
Will do.

Thank you.
