Increase _DW_ENV_STRING_SIZE to 257 bytes, this is the maximum size the
utsname fields can be according to the Linux utsname man page.
This seems to be a bit excessive but, this will prevent any possible issue
on future operating system support. It also eliminates a bogus warning when
compiling using gcc 9 and higher, which I believe is this gcc bug:
warning: ‘__builtin_strncpy’ output may be truncated copying 64 bytes from a string of length 64 [-Wstringop-truncation]
