tests: use basic format code "%Y" instead of "%s" for test portability

On Windows, strftime() doesn't support format code "%s", and it causes
"invalid format string" error.

    https://msdn.microsoft.com/en-us/library/fe06s4ak.aspx

test-command-template.t examines not seconds value in UTC, but
arithmetic calculation. Therefore, using format code "%Y" instead of
"%s" should be reasonable.

FYI:

- Python standard library reference doesn't list "%s" up in format
  code list required for "C standard (1989 version)", even though it
  also mentions that additional format codes are required for "C
  standard (1999 version)"

  https://docs.python.org/2.7/library/datetime.html#strftime-and-strptime-behavior

- The Open Group Base Specifications Issue 7 (IEEE Std 1003.1-2008,
  2016 Edition) doesn't require strftime to support format code "%s"

  http://pubs.opengroup.org/onlinepubs/9699919799/functions/strftime.html

- "man strftime" of (Open/Oracle) Solaris and Mac OS X (= UNIX
  certified OSs) describes about format code "%s"

Initial setup.

  $ hg init repo
  $ cd repo
  $ touch thefile
  $ hg ci -A -m 'Initial commit.'
  adding thefile

Create a tag.

  $ hg tag branchortag

Create a branch with the same name as the tag.

  $ hg branch branchortag
  marked working directory as branch branchortag
  (branches are permanent and global, did you want a bookmark?)
  $ hg ci -m 'Create a branch with the same name as a tag.'

This is what we have:

  $ hg log
