RFR : 7149608 (tz): Default TZ detection fails on linux when symbolic links to non default location used.

Issue seen on somewhat irregular linux system configuration where /etc/localtime is a symbolic link to a directory outside of /usr/share/zoneinfo.

In past, when a symbolic link was seen, the end target file was assumed to be under /usr/share/zoneinfo and a string comparison match was attempted. We need to factor in the case where symbolic link points to any other location and match the end target file with a TZ file from
/usr/share/zoneinfo via findZoneinfoFile function.
