make-mod-scripts: Fix a rare build race condition

There is a build break which rarely happens but is seen often enough
with 4.1 kernel based builds

/bin/sh: 1: scripts/basic/fixdep: Permission denied
scripts/Makefile.host:124: recipe for target 'scripts/dtc/srcpos.o' failed
make[3]: *** [scripts/dtc/srcpos.o] Error 126

this patch sequences the build targets so it can work reliably with
different kernel versions

Divide the target into scripts_basic scripts is not
strictly necessary and was simply what was used for
testing on kernel 4.1, which is quite an old kernel

perhaps just using scripts is sufficient, but it is not tested to not
known will cause the build race as seen above.
