The mode permissions for character, block, and pipe devices were
previously set to 0777, which is overly permissive and not in line
with standard practice. This change reduces the permissions to 0666,
restricting execute permissions while still allowing read/write access.
Changes:
- Adjusted permissions for character/block/pipe devices from 0777 to 0666.

This change addresses a potential out-of-memory access issue in the
devfs filesystem component. The issue arises when the `rt_malloc`
function allocates memory for a path string without accounting for
the null terminator, leading to undefined behavior.
As the manual documented:
> DESCRIPTION
> The strlen() function calculates the length of the string pointed to
> by s, excluding the terminating null byte ('\0').
To fix this, the memory allocation size was increased by one byte
to ensure space for the null terminator. This prevents potential
out-of-memory access and ensures proper string termination.
