sys/linux: cover multi-uprobes for BPF_LINK_CREATE
Upstream, commit [1] added support for multi-uprobe links, to speed up
the attachment of uprobes BPF programs by attaching in batches. This
commit covers the same in syzkaller.
Field path is a path to the binary, offsets are the offsets to attach to
in the binary, and cnt is the number of uprobes to attach to. Field
ref_ctr_offsets is a bit trickier as it can point to an array of
reference counters; I limited those to 0--5 as they are not expected to
be large.
