Use getcwd() which is more reliable than $_SERVER['PWD']

Browse source 
Summary:
in arcanist we are using $_SERVER['PWD'], but in some cases it
is not returning the correct result. For example, when I'm using
PhpStorm (an php IDE) to launch the script, $_SERVER['PWD'] returns the
path of the binary of the IDE:
/home/jungejason/tools/PhpStorm-107.658/bin, not the path where arcanist
is at. getcwd() returns the correct value.

One difference between getcwd() and $_SERVER['PWD'] is that getcwd()
resolves symlink where $_SERVER['PWD'] does not. From what I can see,
using realpath should work.

Test Plan:
* ran arcanist as normal and it worked;
* run arcanist in PhpStorm and it worked.
* created a symlink pointing to the repository inside which
I ran the arc command, and it worked.
* created a symlink pointing to arcanist project, run `.
* resources/shell/bash-completion`  and it worked
