Sunny 9856eae61f libc/libvsprintf: fix vsnprintf bug with "%e" 
For "%e" conversion, the exponent always contains at least two digits.
That means if the value is zero, the exponent is 00, not 0.

Such as code:
  printf(buffer, sizeof(buffer), "%e", 1.232323232323);
  printf(buffer, sizeof(buffer), "%e", 12.32323232323);
  printf(buffer, sizeof(buffer), "%e", 123.2323232323);

Expected output:
  1.232323e+00
  1.232323e+01
  1.232323e+02

But real output:
  1.232323e+0
  1.232323e+1
  1.232323e+2
