nsis: Improved support for parallel installation of 32 and 64 bit code

32 and 64 bit variants of QEMU already had different default installation directories, but used a common registry key for saving the choosen directory. This is confusing for users who want to install both variants, so fix it by using different registry keys. Signed-off-by: Stefan Weil <[email protected]>
