installLisk.sh not working on High Sierra

[RachBLondon]

I have been trying to run the binary test node on OS 10.13.4 and I keep running in to the following issue:

Coldstarting Lisk for the first time
√ Postgresql started successfully.
X Failed to create Postgresql user.
Installation failed. Cleaning up...

@Nazgolze spent some time looking at this yesterday.

@RachBLondon can you please provide some more info:

• what version are you trying to use
• command you're using
• whether you've got postgres running locally

[fchavant]

Looks like the binaries we ship are linked against postgresql 10 but we provide 9.6 libraries; oniguruma is also missing (or rather should be explicitely disabled at runtime)

[fchavant]

This issue will be solved by #314 (getting rid of postgres 10) and #316

[fchavant]

Won't fix: #317
