toolchain-shar-extract.sh: remove checkbashism

Fixed when sh is bash:
$ sh ./tmp/deploy/sdk/poky-glibc-x86_64-core-image-minimal-core2-64-toolchain-1.8+snapshot.sh
Poky (Yocto Project Reference Distro) SDK installer version 1.8+snapshot
===========================================================
./tmp/deploy/sdk/poky-glibc-x86_64-core-image-minimal-core2-64-toolchain-1.8+snapshot.sh: 77: read: Illegal option -e
You are about to install the SDK to "/opt/poky/1.8+snapshot". Proceed[Y/n]? ../SDK2
Installation aborted!

There is ony one bashism "read -e" in toolchain-shar-extract.sh, but
'-e' is useless here, so remove it and use /bin/sh.
