Makefile: use SHELL_PATH when running generate-cmdlist.sh

Non-POSIX shells, such as /bin/sh on SunOS, do not support $((...))
arithmetic expansion or $(...) command substitution needed by
generate-cmdlist.sh.  Make sure that we use a POSIX compliant shell
$(SHELL_PATH) when running generate-cmdlist.sh.
