hardware/beaglelogic: Don't include incorrect header <sys/errno.h>

The libc's errno API[1] comes from <errno.h>, not <sys/errno.h>.
On musl-libc, a warning is produced when the latter is used:

In file included from src/hardware/beaglelogic/beaglelogic.h:26,
                 from src/hardware/beaglelogic/protocol.c:33:
/usr/include/sys/errno.h:1:2: warning: #warning redirecting incorrect #include <sys/errno.h> to <errno.h> [-Wcpp]
    1 | #warning redirecting incorrect #include <sys/errno.h> to <errno.h>
      |  ^~~~~~~

Is it not necessary to change <sys/errno.h> to <errno.h>, because
individual C files in the beaglelogic driver already include <errno.h>.
