libevent: always autogen.sh (#40945)

The libevent release tarballs ship with a `configure` script generated by an old `libtool`. The `libtool` generated by `configure` is not compatible with `MACOSX_DEPLOYMENT_VERSION` > 10. Regeneration of the `configure` scripts fixes build on macOS. 

Original configure contains:
```
    case $host_os in
    rhapsody* | darwin1.[012])
      _lt_dar_allow_undefined='$wl-undefined ${wl}suppress' ;;
    darwin1.*)
      _lt_dar_allow_undefined='$wl-flat_namespace $wl-undefined ${wl}suppress' ;;
    darwin*) # darwin 5.x on
      # if running on 10.5 or later, the deployment target defaults
      # to the OS version, if on x86, and 10.4, the deployment
      # target defaults to 10.4. Don't you love it?
      case ${MACOSX_DEPLOYMENT_TARGET-10.0},$host in
        10.0,*86*-darwin8*|10.0,*-darwin[91]*)
          _lt_dar_allow_undefined='$wl-undefined ${wl}dynamic_lookup' ;;
        10.[012][,.]*)
          _lt_dar_allow_undefined='$wl-flat_namespace $wl-undefined ${wl}suppress' ;;
        10.*)
          _lt_dar_allow_undefined='$wl-undefined ${wl}dynamic_lookup' ;;
      esac
```

After re-running `autogen.sh`:
```
    case $host_os in
    rhapsody* | darwin1.[012])
      _lt_dar_allow_undefined='$wl-undefined ${wl}suppress' ;;
    darwin1.*)
      _lt_dar_allow_undefined='$wl-flat_namespace $wl-undefined ${wl}suppress' ;;
    darwin*)
      case $MACOSX_DEPLOYMENT_TARGET,$host in
        10.[012],*|,*powerpc*-darwin[5-8]*)
          _lt_dar_allow_undefined='$wl-flat_namespace $wl-undefined ${wl}suppress' ;;
        *)
          _lt_dar_allow_undefined='$wl-undefined ${wl}dynamic_lookup' ;;
      esac
```
