[PATCH 1/3] meta: add search, replace strings to export2json

[brian avery <brian.avery@intel.com>]

We want to be able to save relative paths so that we can relocate the
deploy dir images and kernels, yet still have qemu and testimage work
correctly.  This extends export2json with 2 named arguments so a
search/replace operation can be done to remove the leading path.
