doc: Correct documentation of install-time environment variables
Since approximately PostgreSQL 10, it is no longer required that environment variables at installation time such as PERL, PYTHON, TCLSH be "full path names", so change that phrasing in the installation instructions. (The exact time of change appears to differ for PERL and the others, but it works consistently in PostgreSQL 10.) Also while we're here document the defaults for PERL and PYTHON, but since the search list for TCLSH is so long, let's leave that out so we don't need to maintain a copy of that list in the installation instructions.
