Fix "No such file or directory" error in sysroot_ld_path.sh if ld.so.conf include pattern doesn't match any file.

Sometimes ld.so.conf has pattern include like "include ld.so.conf.d/*.conf",
but there is no files that match pattern. In this case "for" loop in process_ld_so_conf
function fails with error "No such file or directory".
This patch uses "ls" to check that pattern matches at least one file.
