libffi: bump to 3.4.2

Remove both patches as they have been upstreamed.
This new release is only available on Github and does not ship configure
or Makefile, so autoreconf is needed.

-Subject: [PATCH] powerpc: fix build failure on power7 and older (#532)
-
-Build failure looks as:
-```
-libtool: compile:  powerpc-unknown-linux-gnu-gcc \
-    -O2 -mcpu=powerpc -mtune=powerpc -pipe ... -c src/powerpc/ffi.c ...
-In file included from src/powerpc/ffi.c:33:
-src/powerpc/ffi_powerpc.h:65:9: error: '__int128' is not supported on this target
-   65 | typedef __int128 float128;
-      |         ^~~~~~~~
-```
-
-The fix avoids using __int128 in favour of aligned char[16].
