Makefile macOS: generate symbols in GUI bundle

Moving just the X.dSYM directory isn't enough since the executable is
identified by name inside the .dSYM tree. But it may be possible to move
the symbols to the "main" tree, since the subtree mimics the hierarchy, eg.
for uv, the symbols are in uv.dSYM/Contents/Resources.
