tools: mkimage: Check for datafile when type is script
If generating a script image and no datafile has been passed in, mkimage
dies with SIGSEGV:
#0 __strchr_sse2 () at ../sysdeps/x86_64/multiarch/../strchr.S:32
#1 0x0000000000403818 in main
at tools/mkimage.c:503
Add explicit test for datafile to fix this.
