package/nfs-utils: fix printfs format build failure on 64-bits platforms

Add 2 upstream patches from nfs-utils that fix build failures on
64-bits where time_t is assumed to be a long long when passed to
printf("%ld"), but that is not always true, so in these patches the
author (Petr) uses PRIu64 tag.

Fixes:
