libpayload: Start using only internal and compiler headers.

When building other payloads with lpgcc the -nostdinc flag was injected into
CFLAGS, but when building libpayload itself some headers were being used from
the host system. This change puts -nostdinc into the Makefile and xcompile
script, fixes up one include path in include/inttypes.h, adds the compiler
provided include directory to the include search path, and deletes the two now
redundant stdint.h files.

BUG=None
TEST=With this and other changes, built libpayload and depthcharge for Daisy,
Link, and Fox.
BRANCH=None
