[PATCH bpf 4/6] tools: bpftool: make syntax for program map update explicit in man page

[Jakub Kicinski]

From: Quentin Monnet <quentin.mon...@netronome.com>

Specify in the documentation that when using bpftool to update a map of
type BPF_MAP_TYPE_PROG_ARRAY, the syntax for the program used as a value
should use the "id|tag|pinned" keywords convention, as used with
"bpftool prog" commands.

Fixes: ff69c21a85a4 ("tools: bpftool: add documentation")
