std.Build.Cache.hit: work around macOS kernel bug
The previous commit cast doubt upon the initial report about macOS
kernel behavior, identifying another reason that ENOENT could be
returned from file creation.
However, it is demonstrable that ENOENT can be returned for both cases:
1. create file race
2. handle refers to deleted directory
This commit re-introduces the workaround for the file creation race on
macOS however it does not unconditionally retry - it first tries again
with O_EXCL to disambiguate the error condition that has occurred.
