bus/dpaa: fix build with musl

The header files argp.h and error.h do not exist in musl libc.

Fix build with musl libc by using err(3) instead of
the GNU-specific error(3).

We could have used the identical errx("...: %s", strerror(ret))` but
strerror(3) is not thread-safe and the strerror_r variant has two
incompatible versions, one GNU specific and one XSI-compliant.
Avoid the mess by letting "err" use the thread-local errno.

This also fixes error message for kzmalloc failures which previously
would always have given "Unknown error -1", since that is what
strerror(-1) returns. Let "err" use the proper error message from errno
which is set by kzalloc.
