scripts/oe-buildenv-internal: Add SOCKS5_{USER, PASSWD} to BB_ENV_EXTRAWHITE
If a SOCKS5 gateway is needed for a proxy access like git it might also
require authentication to the proxy via a password and username. Adding
SOCKS5_USER & SOCKS5_PASSWD to BB_ENV_EXTRAWHITE allow for automation
of the authentication request to occur when something like a git fetch
is going through the proxy.
This patch requires the bitbake patch to add extra exportvars so
these variables get passed from Env -> bitbake -> fetcher
