ci: clear and mark MAKEFLAGS exported just once

Browse Source 
Clearing it once upfront, and turning all the assignment into
appending, would future-proof the code even more, to prevent
mistakes the previous one fixed from happening again.

Also, mark the variable exported just once at the beginning.  There
is no point in marking it exported repeatedly.
