git-svn: fix localtime=true on non-glibc environments
git svn uses POSIX::strftime('%s', $sec, $min, ...) to make unix epoch time.
But lowercase %s formatting character is a GNU extention. This causes problem
in git svn fetch --localtime on non-glibc systems, such as msys or cygwin.
Using Time::Local::timelocal($sec, $min, ...) fixes it.

Notes:
lowercase %s format character in strftime is a GNU extension and not widely supported.
POSIX::strftime affected by underlying crt's strftime because POSIX::strftime just calls crt's one.
Time::Local is good function to replace POSIX::strftime because it's a perl core module function.
Document about Time::Local.
http://perldoc.perl.org/Time/Local.html
These are specifications of strftime.
The GNU C Library Reference Manual.
http://www.gnu.org/software/libc/manual/html_node/Formatting-Calendar-Time.html
perl POSIX module's strftime document. It does not have '%s'.
http://perldoc.perl.org/POSIX.html
strftime document of Microsort Windows C Run-Time library.
https://msdn.microsoft.com/en-us/library/fe06s4ak.aspx
The Open Group's old specification does not have '%s' too.
http://pubs.opengroup.org/onlinepubs/007908799/xsh/strftime.html
On my environment, following problems happened.
- msys : git svn fetch does not progress at all with perl.exe consuming CPU.
- cygwin : git svn fetch progresses but time stamp information is dropped.
Every commits have unix epoch timestamp.
I would like to thank git developer and contibutors.
git helps me so much everyday.
Thank you.
