Subject: [PATCH] curl-wolfssl.m4: fix to use the correct value for pkg-config
 directory

Before this patch the `$withval` variable may have contained `yes` or
other unrelated values, instead of the wolfSSL directory configured via
`--with-wolfssl=`.

Fixing:
```
checking for wolfssl options with pkg-config... found
configure: pkg-config --exists wolfssl trace:
---- begin
PKG_CONFIG_PATH: |/home/runner/wolfssl/build/lib/pkgconfig:/home/runner/nghttp3/build/lib/pkgconfig:/home/runner/ngtcp2/build/lib/pkgconfig:/home/runner/nghttp2/build/lib/pkgconfig|
PKG_CONFIG_LIBDIR: |yes/lib/pkgconfig|         <=============== 'yes' used as base directory
trying path: /home/runner/wolfssl/build/lib/pkgconfig for wolfssl
---- end
```

Closes #20943
