compiler_wrapper: remove -grecord-gcc-switches

-grecord-gcc-switches causes the compiler and compiler flags to be
stored in the produced debug information. This causes Goma builds to
be non-deterministic, because the compiler path differs depending
on whether the compiler was run locally or on Goma. This, in turn,
causes cache pollution and needless work. Since we are not in
fact using the information stored by -grecord-gcc-switches, this
change disables it. We can re-enable it when we want to start
using the information, provided we come up with another way to
avoid the issues described earlier.
