[PATCH] kbuild: move bin2c back to scripts/ from scripts/basic/

[Masahiro Yamada]

Commit 8370edea81e3 ("bin2c: move bin2c in scripts/basic") moved bin2c
to the scripts/basic/ directory, incorrectly stating "Kexec wants to
use bin2c and it wants to use it really early in the build process.
See arch/x86/purgatory/ code in later patches."

Commit bdab125c9301 ("Revert "kexec/purgatory: Add clean-up for
purgatory directory"") and commit d6605b6bbee8 ("x86/build: Remove
unnecessary preparation for purgatory") removed the redundant
purgatory build magic entirely.

That means that the move of bin2c was unnecessary in the first place.
