A couple of silly bugs in the non-standard __enable_shared_from_this
extension.

	PR libstdc++/79156
	* include/bits/shared_ptr_base.h (__enable_shared_from_this_base):
	Fix return type.
	(__enable_shared_from_this): Declare __shared_ptr as a friend.
	* testsuite/ext/shared_ptr/1.cc: New test.

Tested powerpc64le-linux, committed to trunk.
