quota: use time64_t internally
The quota subsystem has two formats, the old v1 format using architecture specific time_t values on the on-disk format, while the v2 format (introduced in Linux 2.5.16 and 2.4.22) uses fixed 64-bit little-endian. While there is no future for the v1 format beyond y2038, the v2 format is almost there on 32-bit architectures, as both the user interface and the on-disk format use 64-bit timestamps, just not the time_t inbetween. This changes the internal representation to use time64_t, which will end up doing the right thing everywhere for v2 format.
