Subject: [PATCH 1/2] checksyscalls: fix "here document" handling

"echo" doesn't read from stdin, therefore the checksyscalls script didn't warn
about not implemented system calls anymore since 29dc54c6 "checksyscalls: Use
arch/x86/syscalls/syscall_32.tbl as source".

Use "cat" instead of "echo" which handles this correctly.
