Looking for something starting with '-Wl,-rpath,' isn't good enough,
as someone might give something like '-Wl,--enable-new-dtags,-rpath,/PATH'.
Looking for ',-rpath,' should be safe enough.
We could remove the preloading stuff entirely, but just in case the
user has chosen to given RPATH setting arguments at configuration,
we'd better make sure testing will still work. Fair warning, there
are some configuration options that do not work with preloaded OpenSSL
libraries, such as the sanity checking ones.

The background story is that util/shlib_wrap.sh was setting LD_PRELOAD
or similar platform dependent variables, just in case the shared
libraries were built with -rpath. Unfortunately, this doesn't work
too well with asan, msan or ubsan.
So, the solution is to forbid the combination of shared libraries,
-rpath and any of the sanity analyzers we can configure.
This changes util/shlib_wrap.sh so it only contains the code that sets
LD_PRELOAD when -rpath has been used when configuring.
