pp-many-files: don't drop a preprocessor defines when tcc going to preprocess a next file

in the same pass like
    tcc -E one.c two.c three.c -o combined.i
This will allow to speed up a compilation process by using a commamd like
    tcc -E *.c | tcc -o program.exe -xc -

It looks that multi-times initialization don't affect anything.
Only call to the free_defines(define_start) in tcc_preprocess()
is removed in assumption that free_defines(NULL) in
tcc_cleanup() will free all defines.
