socat: enable termios

fix two cross-compile issue to enable termios:
1. Define ac_cv_ispeed_offset in EXTRA_OECONF to avoid to call AC_TRY_RUN()
on cross-compile environment.
2. fix autoheader to generate *_SHIFT macros

+Subject: [PATCH] fix autoheader for *_SHIFT values.
+
+Upstream-Status: Pending
+
+autoheader would not generate C `#define' statements if
+the first param of AC_DEFINE_UNQUOTED is a shell variable.
+This will cause build failures while enable termios, so
+expand these AC_DEFINE_UNQUOTED from the macro.
