test-parse-date: defines explicit start/end dates for DST

Prior to this patch, DST times where tested by specifying a custom TZ
environment variable that didn't defined DST transition times.

Due to a bug in glibc, the test fail on 32bits platforms that use timezone
files generated by zic from tzcode >= 2014c (glibc >= 2.20).

See https://sourceware.org/bugzilla/show_bug.cgi?id=19738

By defining explicit transition times for DST in the TZ environment variable,
the test is now independant to how the system guess those transition times.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
