[bug#48985] [PATCH] gnu: libressl: Remove search paths.

[Brice Waegeneire <brice@waegenei.re>]

Unlike OpenSSL, LibreSSL hardcode it's certificate bundle and doesn't
allow to specify it through a environment variable.

* gnu/packages/tls.scm (libressl)[configure-flags]: Specify OpenSSL
configuration directory.
[native-search-paths]: Remove it.
* gnu/packages/ntp.scm (openntpd)[configure-flags]: Adjust CAcert
location.
