payloads/external/GRUB2: Sanitize Makefile 

We were explicitly passing CC and TARGET_CC to configure but overwrote
that decision later by passing CC (with the value of TARGET_CC) directly
to a recursive make call. The latter overwrite was introduced because
`unexport` alone doesn't work on variables that were specified on a make
command line (they are added to MAKEOVERRIDES and passed to further re-
cursive make calls).

Instead of unexporting random variables, unexport those that were actu-
ally passed from payloads/external/Makefile.inc and clear MAKEOVERRIDES.
Do not pass OBJDUMP as that is nowhere to be found in the GRUB sources.
And, last but not least, add --disable-werror because building GRUB is
very susceptible to changes in the flex version.
