Yukihiro "Matz" Matsumoto 3dbf5f6e27 build/command.rb: route mrbc output through tempfile to avoid pipe race ...

The previous IO.popen capture of mrbc stdout (`-o-`) is vulnerable
to a Windows MinGW race: with parallel rake (-m), stdout pipe
inheritance can allow unrelated `_pp` build-progress messages from
sibling worker threads to leak into the captured pipe content,
corrupting the generated C file (recently seen as `CC build/...`
text inside gem_test.c, causing compile errors at unrelated lines).

Switch to `mrbc -o <tmpfile>` so the output is materialised in a
file before merging into the destination, fully isolating mrbc
from the parent's STDOUT.
