curl-compilers.m4: fix compiler_num for clang
"clang -dumpversion" always returns "4.2.1", the GCC version that clang was initially compatible to. Use "clang -v" instead, which returns the actual clang version. Fixes https://github.com/curl/curl/issues/1522 Closes https://github.com/curl/curl/pull/1523
