[llvm-lit][test] Fix regex to capture scientific notation

We were seeing an intermittent local test failure of
utils\lit\tests\test-output.py in which the elapsed time output was
being given in scientific notation. Python automatically represents
small floating-point values in scientific notation so I have altered
these tests regex to capture output in that format.
