Currently BPF_BTF_GET_FD_BY_ID requires CAP_SYS_ADMIN, which does not allow running it from user namespace. This creates a problem when freplace program running from user namespace needs to query target program BTF. This patch relaxes capable check from CAP_SYS_ADMIN to CAP_BPF and adds support for BPF token that can be passed in attributes to syscall.
