[RFC] enable alternative installation and log path

[shrik3]

motivation:
(especially for development) we don't want to use sudo all the time. Also it doesn't make sense to hardcode the paths in the program.

what's changing:
the makefile no longer uses sudo for the install target, you may need to run sudo make install if make install fails. Otherwise nothing changes if you don't modify the makefile.

how to install to custom paths:
modify the makefile, and quark will use these paths for qkernel, vdso.so binary paths, config path and log path.

export PREFIX          ?= /home/shrik3/.local
export QBIN_DIR        ?= $(PREFIX)/bin
export QCONFIG_DIR     ?= /home/shrik3/.config/quark
export QLOG_DIR        ?= /tmp/log/quark

and modify the /etc/docker/daemon.json accordingly.

limitations

1. quark doesn't create the QLOG_DIR (yet). We can do it in the makefile.
2. other logs such as used by qservice are still created under the default path /var/log/quark but they can opt in pretty easily.

Could you please add a condition to check which files to copy over? It is annoying to get false negatives. I have a (semi) fix for that in the previous version, maybe do something similar.

Cheers
