Subject: kern: improve assert

Use the ternary operator to implement `assert' like it is done in the
glibc.  The glibcs changelog does not mention the rationale behind
this change, but doing the same seems to improve our IPC performance.

* kern/assert.h (assert): Define macro using the ternary operator.
