fixes bash build.
fixes: https://github.com/fosslinux/live-bootstrap/issues/99 in my usecase (qemu, kernel 3.18.140) around 50% of all builds are failing with a wrong binary hash. the culprit is a varying generation of 'pipesize.h' during: ``` /bin/sh ./psize.sh > pipesize.h ``` normally generated 'pipesize.h' looks like: ``` /* * pipesize.h * * This file is automatically generated by psize.sh * Do not edit! */ #define PIPESIZE 65536 ``` in the error case the last line has 512 instead of 65536. With this change we use a fixed output of the large PIPESIZE.
