scripts/functions: fix endless loop in debug-shell with IO redirection

CT_DEBUG_INTERACTIVE is disabled when stdin, stdout or
stderr are redirected, but the check is only done at
the start of the build and doesn't catch when individual
build commands use redirection. When stdin is redirected
it will cause the debug shell to exit immediately, causing
and endless loop. Thus, save the stdin/our/err file handles
and restore them before invoking the debug shell.

     3 reporter_comment="This is a sample config file for Freescale e500v2 processors (e.g., MPC8548,

     4 MPC8572). It uses eglibc (for e500/SPE patches) and a recent gcc (4.6.0,

     5 for e500v2 DPFP support) and will generate appropriate dual-precision

     6 floating point instructions by default.

     8 Note: If building a Linux kernel with this toolchain, you will want to make

     9 sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE ABI/instructions

    10 from getting into the kernel (which is currently unsupported). At this time,

    11 the kernel build system properly passes those two options, but older kernels

    12 were only passing -mno-spe by default."
