Eric Ackermann 2d3390f866 llext: Fix off-by-one in RISC-V truncation check
The RISC-V architecture-specific relocations need to check whether
each required relocation can fit into the modified instruction's
immediate. All immediates in RISC-V are encoded as two's complement.
The current truncation check has an off-by-one error for checking
the maximum negative distance, as two's complement encoding can
represent a negative value that is the maximum positive value plus
one, causing LLEXT to refuse loading valid code.
This commit adds an additional condition to the check that fixes
the aforementioned issue.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
