Golang symbols in ELF files are different from C/C++
which contains special characters like '*', '(' and ')'.
With generics, things get more complicated, there are
symbols like:
github.com/cilium/ebpf/internal.(*Deque[go.shape.interface {
Format(fmt.State, int32); TypeName() string;
github.com/cilium/ebpf/btf.copy() github.com/cilium/ebpf/btf.Type
}]).Grow
Add " ()*,-/;[]{}" (in alphabetical order) to support matching
against such symbols. Note that ']' and '-' should be the first
and last characters in the %m range as sscanf required.
A working example can be found at this repo ([0]).
