Incorrect `lambdify`? (exponentiation of negative `real`)

`simplify()` moves exponentiation into the modulo operation,
but that apparently changes semantics as per externally-observable side-effects:

```
using SymPy
@syms x::real
@show f_sym = 0.17*x/(abs(x))^(0.6)
@show f_sym(-1)
f = lambdify(f_sym)
@show f(-1)
@show f_sym_simplified = simplify(f_sym)
@show f_sym_simplified(-1)
f_simplified = lambdify(f_sym_simplified)
@show f_simplified(-1)
```
```
f_sym = (0.17x) / abs(x) ^ 0.6 = 0.17*x/Abs(x)^0.6
f_sym(-1) = -0.170000000000000
f(-1) = -0.17
f_sym_simplified = simplify(f_sym) = 0.17*x/Abs(x^0.6)
f_sym_simplified(-1) = -0.170000000000000
DomainError with -1.0:
Exponentiation yielding a complex result requires a complex argument.
Replace x^y with (x+0im)^y, Complex(x)^y, or similar.
