tree-wide: drop DLOPEN_FOO() macros

Since 4c0d8d9673, most dlopen notes are
set at the beginning of the executables. Let's manage all dlopen notes
there, rather than setting them where dlopen is called.

Note that the only exceptions are the LIBBPF_NOTE for networkd and
nsresource. Since dlopen_bpf() is wrapped in an `#if` guard, the notes
are instead set within the corresponding functionality.

As a result, the DLOPEN_FOO() wrapper macros are no longer needed and
can be dropped completely.
