debugfs, tune2fs: Handle daylight savings time when parsing a time string

We need to set tm_isdst to -1 so that mktime will automatically
determine whether or not daylight savings time (DST) is in effect.
Previously tm_isdst was set to 0, which caused mktime to interpret the
time as if it was always not using DST.
