test/e2e: remove FIPS test

First, creating a global file /etc/system-fips was never a good idea for
testing as it affects other running tests at the same time.
And as of a recent change to FIPS mounts[1] we no longer use the file so
the test breaks with c/common v0.61. Instead it uses the kernel file
/proc/sys/crypto/fips_enabled which requires the real fips mode to be
activated and that in turn requires a reboot. As such this is not
somthing that can be tested in upstream CI like that.
