[OE-core] [PATCH] autotools.bbclass: fixed bash build error

[Wenlin Kang]

When build bash, a error occurs, the cause is that autotools uses
improper Makefile.in.in which is from path/gettext/po/ but not bash
itself in bash/po/,so to avoid some error to occur, we should use
package itself Makefile.in.in file if it has.
