t9001: avoid non-portable '\n' with sed

t9001 used a '\n' in a sed expression to split one line into two
lines, but the usage of '\n' in the "replacement string" is not
portable.

The '\n' can be used to match a newline in the "pattern space",
but otherwise the meaning of '\n' is unspecified in POSIX.

- Gnu versions of sed will treat '\n' as a newline character.
- Other versions of sed (like /usr/bin/sed under Mac OS X)
  simply ignore the '\' before the 'n', treating '\n' as 'n'.

For reference see:

As the test already requires perl as a prerequisite, use perl
instead of sed.
