This adds a quick fix so that any if blocks nested inside a if block
with an unmet condition are handled with push(false) even if their
condition is satisfied.
For example, without this modification, upon running create_project.exe
--msvc --disable-cloud --enable-libcurl the block inside
ifdef USE_CLOUD
ifdef USE_LIBCURL
...
endif
endif
in backends/module.mk would get evaluated since it was inside
USE_LIBCURL (=1), leading to unpredictable results.
