tests: change obsolete timestamp to avoid "gmtime()" problem on Windows

Before this patch, "test-obsolete.t" fails on Windows environment,
because strings corresponded to "tm_wday" (day of the week) field are
incorrect.

On POSIX environment, "gmtime()" returns correct "tm_wday" value even
for negative "time_t" value. On the other hand, it returns incorrect
one on Windows environment. At least, "gmtime()" of the Windows
runtime library bundled with Python 2.7.3 does.

According to 9a7d0f7e0561 introducing original timestamp value '56
120', it shouldn't cause negative "time_t" value.

    test-obsolete: remove subminute timezone in test

    Obsmarker format "1" does not supports sub minute timezone. So we
    change the test to something slightly more sensible.

It replaced "-d '56 12'" by "-d '56 120'".

Test merge with no common ancestor:
a: just different
b: x vs -, different (cannot calculate x, cannot ask merge tool)
c: x vs -, same (cannot calculate x, merge tool is no good)
d: x vs l, different
e: x vs l, same
f: - vs l, different
g: - vs l, same
h: l vs l, different
(where same means the filelog entry is shared and there thus is an ancestor!)
