test: remove CMAKE_C_STANDARD

[alfredh]

the current C99 action test is broken

The code is always compiled with C11.

[alfredh]

Example:

alfredh@debian:~/git/re$ cmake -DCMAKE_C_STANDARD=99 .

-> The compiler is still using "-std=c11"

it looks like CMAKE_C_STANDARD is hardcoded in the CMake file.

When building with a C99 compiler the test try_into fails due to missing definitions.

I think both have to be removed, since test is loaded with subdirectory:

This fixes try_into tests: #717

[alfredh]

I guess the compiler will use the default standard, if not specified.

With this change, the C99 CI check should work.

[alfredh]

build failed, as expected:

D:\a\re\re\src\tls\openssl\tls_udp.c(757): error C2220: the following warning is treated as an error
D:\a\re\re\src\tls\openssl\tls_udp.c(757): warning C4013: 'content_type_str' undefined; assuming extern returning int

lets merge the "C99 dbg" first ...

[alfredh]

this should be working now ...
