Makefile: Avoid non-portable GNU sed extension

Browse source 
Use [:space:] instead of \s and \S in regular expression that
determines the sandbox target architecture.  Fixes the build
failure on OpenBSD introduced with commit 4e65ca00f3
("efi_loader: bootmgr: add booting from removable media").

Fixes: f7691a6d73 ("sandbox: allow cross-compiling sandbox")
