Introduce alpm_time_t type

This will always be a 64-bit signed integer rather than the variable length
time_t type. Dates beyond 2038 should be fully supported in the library; the
frontend still lags behind because 32-bit platforms provide no localtime64()
or equivalent function to convert from an epoch value to a broken down time
structure.
