    Remove ref_dynamic_nonweak added by accident

used pr11138-1.map to build libpr14862.so by accident and pr14862.map
should be used instead.  The difference is

pr11138-1.map:

VERS_1 {
  global: bar; foo;
  local: *;
};

vs

pr14862.map:

VERS_1 {
  global: bar;
  local: *;
};

Since only "bar" is used, it didn't cause test failure.  Use pr14862.map
to build libpr14862.so as intended.

	PR ld/14862
	* ld-elf/shared.exp: Replace pr11138-1.map with pr14862.map
	when building libpr14862.so.
