kheaders: remove the last bashism to allow sh to run it
'pushd' ... 'popd' is the last bash-specific code in this script. One way to avoid it is to run the code in a sub-shell. With that addressed, you can run this script with sh. I replaced $(BASH) with $(CONFIG_SHELL), and I changed the hashbang to #!/bin/sh. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
