Shell: Quick fix to not freeze for multiple seconds

When sync is writing to disk, it reserves whole disk to itself.
This commit makes Shell to read username only once from getpwuid().
We used to get username every time prompt was printed.

Kernel/LibC: remove PATH resoltion from kernel
...
I have no idea why I had made PATH environment variable parsing
to be part of the kernel. Now the shell does the parsing and
environment syscall is no longer needed.

Shell: Clean exit on ^D and use getchar()
...
Use getchar() instead of fread(&ch, 1, sizeof(char), stdin). This
is much cleaner.

BuildSystem: Base sysroot is now distributed as a tar ball
...
This allows file and directory permissions work as intended.
cmake is now filled with 'sudo' but with sudo timeout this should be
fine.

Kernel: Userspace signal handlers are now called one at a time
...
I added a syscall for telling the kernel when signal execution has
finished. We should send a random hash or id to the signal trampoline
that we would include in the syscall, so validity of signal exit can
be confirmed.
