fix socat integration CI

[samuel40791765]

socat started cutting off the tests prematurely if the test hadn't finished yet with these commits:

• https://repo.or.cz/socat.git/commitdiff/74d03b37da1226f5d76d1503487d7cd8b90c4d80
• https://repo.or.cz/socat.git/commitdiff/b5b9ee0031eb0f38a71b44a45723d728265ee1bd

+if [ -z "$val_t" ]; then
+    # Determine the time Socat needs for an empty run
+    $SOCAT /dev/null /dev/null         # populate caches
+    MILLIs=$(bash -c 'time socat /dev/null /dev/null' 2>&1 |grep ^real |sed 's/.*m\(.*\)s.*/\1/' |tr -d ,.)
+    while [ "${MILLIs:0:1}" = '0' ]; do MILLIs=${MILLIs##0}; done      # strip leading '0' to avoid octal
+    [ -z "$MILLIs" ] && MILLIs=1
+    [ "$DEFS" ] && echo "MILLIs=\"$MILLIs\" (1)" >&2
+
+    # On my idle development computer this value flaps from 0.001 to 0.004
+    # 0.001 lets many tests fail, so we triple the result
+    MILLIs=$((3*MILLIs))
+    [ "$DEFS" ] && echo "MILLIs=\"$MILLIs\" (2)" >&2
+    MICROS=${MILLIs}000

A lot of tests are related to specific warnings that socat emits based on the openssl version not supporting certain things. My suspicion is that the additional time when writing to the logs breaks the 3 millisecond threshold and socat determines that we've failed the test. Extending this time threshold to 50 milliseconds gets past things.
