Fix for building nano dump under arm64 (Apple Silicon & co)

[k1ubi]

Description

Fix nanodump build failure on ARM/Kali by using the native strip tool for the Linux scripts/restore_signature helper instead of x86_64-w64-mingw32-strip. This prevents Unable to recognise the architecture errors when compiling the Extension-Kit on non‑x86_64 hosts while keeping MinGW stripping for Windows artifacts unchanged.

Fix

Under Extension-Kit/Creds-BOF/nanodump

Change these two lines:
@$(GCC) source/restore_signature.c -o scripts/restore_signature -static -s -Os @$(STRIP_x64) --strip-all scripts/restore_signature

into:
@$(GCC) source/restore_signature.c -o scripts/restore_signature -static -s -Os @strip --strip-all scripts/restore_signature
