libcamera: base: utils: Drop defopt

Browse source 
utils::defopt causes compilation issues on gcc 8.0.0 to gcc 8.3.0,
likely due to bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86521
that was fixed in gcc 8.4.0. gcc 8.3.0 may be considered old (libcamera
requires gcc-8 or newer), but it is shipped by Debian 10 that has LTS
support until mid-2024.

As no workaround has been found to fix compilation on gcc 8.3.0 while
still retaining the functionality of utils::defopt, remove it from the
libcamera base library. This change could be reverted once support for
gcc-8 will be dropped.
