[PATCH] debuginfod/debuginfod-client.c: correct string format on 32bit arches with 64bit time_t

[Alexander Kanavin]

From: Alexander Kanavin <alex.kanavin@gmail.com>

Use intmax_t to print time_t

time_t is platform dependent and some of architectures e.g.
x32, riscv32, arc use 64bit time_t even while they are 32bit
architectures, therefore directly using integer printf formats will not
work portably, use intmax_t to typecast time_t into printf family of
functions.

musl 1.2.0 and above uses time64 on all platforms; glibc 2.34 has added support for
time64 (which might be enabled by distro-wide CFLAGS), with possibly
2.35 or 2.36 making it enabled by default.

Use a plain int for scanning cache_config, as that's what the function
returns.
