Subject: [PATCH 1/3] build: fix setting AM_CONDITIONAL for brotli and zstd

As the with_{libbrotli,libzsttd} variables are unset if configured
with --without-{brotli,zstd}, check the unequality to "no" doesn't
work; use explicit matching with "yes" instead.

Subject: [PATCH 3/3] build: add liboqs in Requires.private in gnutls.pc if
 needed

When --with-liboqs is specified and liboqs cannot be dlopen'ed, it
will be linked at build time. In that case gnutls.pc should indicate
that through Requires.private.
