package/erlang: bump to version 22.2

The issue fixed by 0003-Link-with-LDLIBS-instead-of-LIBS-for-DED.patch (ERL-529)
has been fixed since OTP20.3 (a5cbcbdb85) and is no longer required.

OTP provides wrapper scripts (otp_build and configure) which perform tasks
previously handled directly by autotools i.e. autoreconf.

[Thomas:
 - drop the save_bootstrap step, which is not needed
 - properly run the autoconf step for both the host and target
   variants]
