Bug #1679: rb_w32_getenv() invalidates previous environment pointers

=begin
 On Windows turning on page heap (gflags -p /enable ruby.exe /full) revealed that environment pointers returned by rb_w32_getenv() get invalidated on the next call to this function due to the freeing of the environment buffer.
 In particular getenv("RUBYLIB_PREFIX") in rubylib_mangle() frees getenv("RUBYLIB") fetched in ruby_init_loadpath(). This bug is also present in ruby 1.9.1-p129.
 
 The workaround - the RTL version of getenv() - worked fine for me so far.
