The decompressor has its own implementation of the string functions,
but has to include the right header to get those, while implicitly
including linux/string.h may result in a link error:
arch/x86/boot/compressed/kaslr.o: In function `choose_random_location':
kaslr.c:(.text+0xf51): undefined reference to `_mmx_memcpy'
This has appeared now as kaslr started using memcpy. Other files in the
decompressor already do the same thing.
Fixes: d52e7d5a952c ("x86/KASLR: Parse all 'memmap=' boot option entries")
