Avoid 'Unexpected heap growth' in 64-bit multi-threaded gctest if n_tests=1

* tests/test.c [!VERY_SMALL_CONFIG && CPP_WORDSZ==64] (check_heap_stats):
Increase max_heap_sz initial value by ~8.7% (so that the ratio of
max_heap_sz initial values between 32-bit and 64-bit targets
is the roughly same as exists for VERY_SMALL_CONFIG).
