imx-dpu-g2d: Fix strtol() overflow check in getSystemEnvInt()

getSystemEnvInt() stores the strtol() result in an int and then compares
it against LONG_MAX/LONG_MIN. On LP64 the value is truncated first, so
the ERANGE check can never trigger, and clang fails the build:

  os/linux/g2d_utils.c:33:31: error: result of comparison of constant
  9223372036854775807 with expression of type 'int' is always false
  [-Werror,-Wtautological-constant-out-of-range-compare]

Add a patch that keeps the value in a long, rejects values outside the
int range and narrows explicitly on return.

Tested with bitbake imx-dpu-g2d on imx8qm-var-som using clang.
