[PATCH] kbuild: fix spurious error from find when generating asm-headers

[H. Nikolaus Schaller]

The *.h pattern should be quoted or we may see errors like

  find: paths must precede expression: elf.h
  Usage: find [-H] [-L] [-P] [-Olevel] [-D help|tree|search|stat|rates|opt|exec] [path...] [expression]

if the working directory contains some *.h files.

This was found in a cross-compilation environment.

Fixes: 2d69b891e6461 ("kbuild: Support generated asm-headers in subdirectories")
