osx: fix bundle on macOS High Sierra (10.13)

Apple slightly changed the App bundle mechanism which broke wrapper
scripts that invoke the actual binary. it caused the bundle to always
open a new instance of mpv instead of reusing the currently running one.

just removing the wrapper script would lead to several regressions, so
it was replaced with a symlink to the bundle binary. detection if mpv
was started from the bundle was replaced by comparing the execution name
of the binary, eg the name of the symlink "mpv-bundle". additionally,
because we load a standard config from the Resources folder of the
bundle again, we prevent that config from being loaded if mpv wasn't
started via the bundle. the psn argument has to be removed manually
again.

the ability of loading your standard shell environment has been removed
with the wrapper. a substitution will be added with another commit. as a
side effect this fixes an issues when zsh was used with common NodeJS
configuration scripts.

Fixes #4926 #4866
