Use GLOG_* environment variables even when gflags is installed.
Define GLOG_DEFINE_*, which checks if the GLOG_* environment variable
is defined. If defined, GLOG_DEFINE_* passes the value and otherwise,
it passes the original default value. In this way, GLOG_DEFINE_* macro
uses the value specified by gflags first, then GLOG_* environment
variables, and finally it uses the default value if neither of them are
specified.
