Rework the container to build and run cppcheck as a normal user.  Use
heredocs for readability and use apt-get --no-install-recommends to
keep the size down.

Changed the libpcre3-dev dependency to libpcre3, as the -dev package
is only needed for building, not for running.

With the cleanups, the size of the container is reduced from 882MB to
782MB.

I tried updating cppcheck to the latest upstream version (2.15.0) but
it reports misra errors like:

    xen/common/sched/cpupool.c(0,0):internalError:error:Bailing out from analysis: Checking file failed: Failed to execute addon 'misra' - exitcode is 1
    [...]
    xen/arch/arm/decode.c(220,10):misra-config:error:Because of missing configuration, misra checking is incomplete. There can be false negatives! Variable 'type' is unknown

The output log xen-cppcheck.txt from job #8164274901 which uses
cppcheck 2.15.0 can be found at:
https://gitlab.com/xen-project/people/javimerino/xen/-/jobs/8164274901/artifacts/browse

Therefore, I'm keeping cppcheck at 2.7, which aligns with what
docs/misra/cppcheck.txt says is the last tested version.

Yes, better to do the upgrade separately
