Running `uname -m` on Apple silicon machines always results in `arm64`,
regardless if Bash is running in Rosetta 2 emulation or natively.
Check if scancode and configure is running in emulation mode (see [1]),
before relaunching it, to avoid an infinite loop.

Calling `bash -c` with `$@` results in only the first parameter being
passed to the subshell. Use `$*` to ensure all parameters are correctly
passed to the Rosetta 2 emulated subshell.

This commit carries over a patch applied to the scancode and configure
scripts to ensure that extractcode can work correctly in X86 emulated
mode on Apple ARM silicon,

* Only relaunch extractcode when not in emulation mode
