Bug 1531632 - Initialize environment variables before loading libxul. r=snorp

Browse Source 
There are at least two known side effects of initializing it after
loading libxul:
- We can't set LLVM_PROFILE_FILE for the instrumentation part of PGO to
  make the compiler-rt static initializer pick it.
- We can't set MOZ_DEBUG_LINKER to enable the linker debug log (which
  used to work when environment variables were set earlier).
