Use secp256k1_fe_equal_var in secp256k1_fe_sqrt_var.
...
In theory this should be faster, since secp256k1_fe_equal_var is able to
shortcut the normalization. On x86_64 the improvement appears to be in
the noise for me. At least it makes the code cleaner.

Using AC_CHECK_DECL, the generated test tries to cast the function to void.
Clang doesn't allow that for builtins.
