One-line summary: Show tls library name in status

Additional description (if needed): This could also fix .status showing something like: Tcl library: //zipfs:/lib/tcl/tcl_library instead of the name/path of the tcl lib dladdr() is not POSIX, but it is available under solaris, linux and bsd and we can autoconf for it.

Test cases demonstrating functionality (if applicable): .status Before:

[...]
Tcl library: /usr/lib/tcl8.6
Tcl version: 8.6.16 (header version 8.6.16)
Tcl is threaded.
TLS support is enabled.
TLS library: OpenSSL 3.6.0 1 Oct 2025 (header version OpenSSL 3.6.0 1 Oct 2025)
[...]

After:

[...]
Tcl library: /usr/lib/tcl8.6
Tcl version: 8.6.16 (header version 8.6.16)
Tcl is threaded.
TLS support is enabled.
TLS library: /usr/lib/libssl.so.3
TLS version: OpenSSL 3.6.0 1 Oct 2025 (header version OpenSSL 3.6.0 1 Oct 2025)
