Set ccache size before building

[zcbenz]

The cache miss is very high in CUDA build recently:

Cacheable calls:    415 / 415 (100.0%)
  Hits:             180 / 415 (43.37%)
    Direct:         176 / 180 (97.78%)
    Preprocessed:     4 / 180 ( 2.22%)
  Misses:           235 / 415 (56.63%)
Local storage:
  Cache size (GiB): 0.6 / 5.0 (11.22%)
  Cleanups:         124
  Hits:             180 / 415 (43.37%)
  Misses:           235 / 415 (56.63%)
Statistics zeroed
Set cache size limit to 400.0 MB
Cleaning... 100.0%

It seems that ccache removed recent caches when doing cleaning, setting cache size being building should be able to make things work better, also increase the cache size a bit.
