NSIS: Quote uninstaller path when executing it in a shell
Protect our `$0` reference in the shell as `"$0"`. Otherwise it works
with a space in the path only due to an insecure Windows feature.
Prior to this fix, any installer using the option added by commit
v2.8.9~234^2 (Added CPACK_NSIS_ENABLE_UNINSTALL_BEFORE_INSTALL,
2011-06-11) exposes a local privilege escalation vulnerability.
