package/libgpiod: enable the kernel GPIO ABI v1

Browse Source 
Unlike libgpiod2, this version of libgpiod relies on the deprecated GPIO
ABI version 1. This ABI used to be enabled by default. However, since
Linux 7.1-rc1 (commit 7673e4c7f7f9 "Do not enable the v1 uAPI by
default"), this is not the case anymore. Failing to enable the ABI
results in a non-functional libgpiod. For instance:

    # gpioinfo
    gpioinfo: error creating line iterator: Invalid argument

Fix this by enabling the ABI v1 in LIBGPIOD_LINUX_CONFIG_FIXUPS.
