[PATCH] build: Place cache file in build directory

[Karel Gardas]

Hello Sebastian,

sorry for late warning, but this patch breaks wscript on Ubuntu 20.04
LTS. It looks like bldnode is not part of the ctx variable. At least
bsp_defaults and bsp_list commands are broken by it. The output looks as:

$ ./waf bsp_list
Traceback (most recent call last):

The error is the same and independent of python2/python3 execution.
Reverting the patch helps here.

Thanks,
Karel
