autotools.bbclass: fix cp error for empty dir 

the .../usr/share/aclocal is empty for build from scratch. so avoid cp
error if the directory is empty.

Fixes this error, which is thrown before pseudo is built:

| cp: cannot stat
`/builddisk/build/build0/tmp/sysroots/x86_64-linux/usr/share/aclocal/*':
No such file or directory
NOTE: package libtool-native-2.4.2-r0.0: task do_configure: Failed
