package/libopenssl: add (proposed) upstream fix for parallel installation

The openssl developers have proposed a fix for the parallel installation
issue worked around by commit 27ab880ebb9a (package/libopenssl do not build
in parallel).

Add the fix here so the workaround can dropped again.

+Subject: [PATCH] Serialize install process to avoid multiple make depend
+ operations
+
+If make install is run with a large -j value (make install -j N , where
+N > 1)
+
+We can run into a situation in which the install fails because multiple
+make depend operations are running in parallel, which will fail due to
+makefile rewriting.
+
+Serialize the install process to guarantee that those operations don't
+step on one another
+
+Fixes # 27074
