import-checker: add xargs like mode

Before this patch, "import-check.py" is invoked via "xargs" in
"test-module-imports.t", but it doesn't ensure that
"import-checker.py" is certainly invoked with all mercurial specific
files at once.

"xargs" may invoke specified command multiple times with part of
arguments given from stdin: according to "xargs(1)" man page, this
dividing arguments is system-dependent.

This patch adds "xargs" like mode to "import-checker.py".

This can ensure that "import-checker.py" is certainly invoked with all
mercurial specific files at once in "test-module-imports.t". This is
assumed by subsequent patches.

#   seq START STOP        [START, STOP] stepping by 1
#   seq START STEP STOP   [START, STOP] stepping by STEP
