Make it possible to disable udev in the content API on linux

This is useful for embedded linux setups, which often don't include udev support.

TEST=Build content_shell on linux with use_udev=0 then run ldd on output binaries to verify libudev is not listed (and is listed if built with use_udev=1 or unspecified)

Fixes an issue where new credit card/address autofill details weren't always been created.

BUG=305919
TEST=Navigate to chrome://settings/autofill, and add a new credit card.
Click edit on the newly created row, and then close the edit overlay by
clicking the cross in the top right, or by pressing <Esc>. Now, add a
new credit card. This patch ensures that the new card is added (previously,
the original card would be updated instead). This also applies to addresses.
