libtool: add bash to RDEPENDS_libtool

* Set CONFIG_SHELL="/bin/bash"
* Add bash to RDEPENDS_libtool

We had already set CONFIG_SHELL="/bin/bash" for libtool-native,
libtool-cross and nativesdk-libtool, now also set for target libtool, if
we don't set this, libtool would use /bin/sh, /bin/bash, /bin/ksh or
/bin/sh5 according to the host, and the build is undetermined, this
patch can fix the problem, libtool is a development tool, rdepends on
bash should not cause toubles (for example, the size of the image)

Have tried to set CONFIG_SHELL="/bin/sh" (/bin/sh -> dash), but there is
still a few bashsim in the output libtool.
