stdlib/tst-strtod-overflow: Bump timeout up yet more

Hi,

In our routine testing I observed that stdlib/tst-strtod-overflow is very
slow, especially on targets using soft-float or QEMU (where soft-float is
used internally), enough to time out even on slow boards we have that have
TIMEOUTFACTOR already bumped from the default of 1 up to 75.

No other test case requires such a long timeout -- all the other
succeeding cases fit within their timeouts scaled by TIMEOUTFACTOR on
these boards. As such I think it's counter-productive to require
TIMEOUTFACTOR to be set as high as 450 globally for this lone outlier as
the value affects overall testing duration where there are test cases that
genuinely time out due to a defect. Therefore I propose the following
change that makes stdlib/tst-strtod-overflow pass on these slow boards
with TIMEOUTFACTOR of 75.

OK to apply?
