+Fix a Y2038 test failure on systems where time_t is a signed 32-bit value:

+Subject: [PATCH] tests: Avoid overflowing signed 32 bit time_t.
+
+* tests/openpgp/quick-key-manipulation.scm: Use expiration times in
+the year 2038 instead of 2105 to avoid overflowing 32 bit time_t.
+time_t is used internally to parse the expiraton time from the iso
+timestamp.
