[Buildroot] [PATCH] libcurl: security bump to version 7.61.0

[Baruch Siach]

Fixes CVE-2018-0500: curl might overflow a heap based memory buffer when
sending data over SMTP and using a reduced read buffer.

Drop upstream patch.

Add reference to tarball signature key.

Drop CRYPTO_lock seed. Removed from configure script since 7.45.

-Subject: [PATCH 1/1] Fix link with ssh2 built with a static mbedtls
-
-The ssh2 pkg-config file could contain the following lines when build
-with a static version of mbedtls:
-   Libs: -L${libdir} -lssh2 /xxx/libmbedcrypto.a
-   Libs.private: /xxx/libmbedcrypto.a
-
-This static mbedtls library must be used to correctly detect ssh2
-support and this library must be copied in libcurl.pc otherwise
-compilation of any application (such as upmpdcli) with libcurl will fail
-when trying to found mbedtls functions included in libssh2.
-So, replace pkg-config --libs-only-l by pkg-config --libs.
-
-Fixes:
