Support replacing MODULE_PATHNAME during extension script file execution.

This avoids the need to find a way to make PGXS' .sql.in-to-.sql rule
insert the right thing.  We'll just deprecate use of that hack for
extensions.

<para>
The value of this parameter will be substituted for each occurrence
of <literal>MODULE_PATHNAME</> in the script file(s). If it is not
set, no substitution is made. Typically, this is set to
<literal>$libdir/<replaceable>shared_library_name</></literal> and
then <literal>MODULE_PATHNAME</> is used in <command>CREATE
FUNCTION</> commands for C-language functions, so that the script
files do not need to hard-wire the name of the shared library.
