libc-package.bbclass: should not rm scsi/*.h

{e}glibc should install the scsi/*.h files, which are needed by hal.
Currently hal can build because eglibc-initial (which has its own do_install)
installs the files. In future eglibc will have its own sysroot, so hal
won't build.

BTW: in OE side, eglibc's do_install also doesn't remove the files.
