RFR: 8255239: The timezone of the hs_err_pid log file is corrupted in Japanese locale

[Calvin Cheung]

Please review this simple fix by using the wide char version of strftime, i.e. wcsftime, to convert the timezone into a wide character string. After that, converting the wide character string back to multi-byte string before printing out the time and timezone.

Testing: ran the test case in the bug report manually on:

- Windows with ja, zh-tw, and en locales;

- Linux and Mac OS with en locale.
