cmd/ms: read #P/ps2mouse in a char (not in an int) 

After the removal of dumb push in crt0 (commit 929014ebca5c738d3854758326de7abfb77c1ef1)
the first byte of the c integer is not zeroed anymore (which is correct).

But since ms.c reads and bit-match a single byte in c, when it's an int some test success/fail
due to the state of the unused bytes.

This makes the mouse turn crazy.

So we turn it into a char, so that bitmasks and tests work as expected.
