The current implementation causes inputs listed in an rsp file used with
sbox to be duplicated 3 times in the build.ninja file; once as a
dependency of the rule, once in the rspfile_content field of the rule
with the paths rewritten to be relative to the sandbox, and once in the
rule to write the sbox manifest. When RBE is enabled it also gets a
fourth copy in the list of files to be treated as inputs by rewrapper.
Reduce this to a single copy by using "$in" for the rspfile_content so
that the files only have to be listed in the input dependencies of the
rule, and then add support to sbox to rewrite the rsp file while copying
it into the sandbox, and pass it to rewrapper as well.

sbox is going to need to read and write response files, move ReadRspFile
to its own package.
