civetweb: Add new recipe with git-based version

Add recipe for CivetWeb: easy to use, powerful, C/C++ embeddable web
server with optional CGI, SSL and Lua support, under MIT license.

CivetWeb provides C and C++ libraries and a standalone server binary.

Choose specific post-v1.10 git revision b8148afe8fa4 which has a fixed
SSL support (depending on OpenSSL v1.0.2).

+Subject: [PATCH] Unittest: Fix missing librt and libm during native compilation
+
+civetweb looks for librt and libm in weird places and for native build
+this fails:
+
+    | ../third_party/lib/libcheck.a(check.c.o): In function `tcase_create':
+    | build/tmp/work/x86_64-linux/civetweb-native/1.10-r0/build/third_party/src/check-unit-test-framework/src/check.c:145: undefined reference to `floor'
+    | build/tmp/work/x86_64-linux/civetweb-native/1.10-r0/build/third_party/src/check-unit-test-framework/src/check.c:148: undefined reference to `floor'
+
+These are needed dependencies so try regular system linkage in such
+case.
