libmbedtls: fix unrecognized compiler option
Prior to this patch when compiling with clang there an error:
error: unknown warning option '-Wno-unused-functions'; did you mean '-Wno-unused-function'? [-Werror,-Wunknown-warning-option]
Fix this by using -Wno-unused-function instead.
Fixes: dfafe507bbef ("Import mbedtls-3.4.0")
