busybox: update to 1.34.1

Update busybox to version 1.34.1, which is a minor
maintenance release. It contains just the two post-1.34.0
upstream patches that we earlier backported plus a few fixes
to awk.

* Remove the two backported upstream patches that are
  now unnecessary.

-Stacy Harper reports that this script:
-
-   test() { . /tmp/bb_test; }
-   echo "export TEST=foo" >/tmp/bb_test
-   test 2>/dev/null
-   echo "$TEST"
-
-correctly prints 'foo' in BusyBox 1.33 but hangs in 1.34.
-
-Bisection suggested the problem was caused by commit a1b0d3856 (ash: add
-process substitution in bash-compatibility mode).  Removing the call to
-unwindredir() in cmdloop() introduced in that commit makes the script
-work again.
-
-Additionally, these examples of process substitution:
-
-   while true; do cat <(echo hi); done
-   f() { while true; do cat <(echo hi); done }
-   f
-
-result in running out of file descriptors.  This is a regression from
-v5 of the process substitution patch caused by changes to evalcommand()
-not being transferred to v6.
