build: fix compatibility with meson 0.41 onwards

Browse Source 
Versions of meson prior to 0.47 flattened the parameters to the
"set_variable" function, which meant that the function could not take
array variables as a parameter. Therefore, we need to disable driver
tracking for those older versions, in order to maintain compatibility
with the minimum supported 0.41 version, and also v0.45 shipped in
Ubuntu 18.04 release.

Fixes: 806c45dd483d ("build: add configuration summary at end of config")
