Fix file path issues with separate output files

[sumanmichael]

Found an issue where some of the special output files weren't being created in the right directories when using OUTPUT_DIR or when the main output file had a path.

The problem was that files like INDEXES_* , AUTOINCREMENT_* , LOGICAL_*, etc. were using simple string concatenation instead of proper path handling. This would cause errors like:

ora2pg -c /etc/ora2pg/ora2pg.conf.dist -t TABLE --input /tmp/input.sql --out /tmp/output.sql --no_header -O DEFAULT_NUMERIC=numeric -O EXPORT_SCHEMA=1

FATAL: Can't open AUTOINCREMENT_/tmp/output.sql: No such file or directory

When processing tables with identity columns like:

CREATE TABLE test_schema.sample_table (
    id NUMBER GENERATED BY DEFAULT AS IDENTITY MINVALUE 1 MAXVALUE 9999999999999999999999999999 INCREMENT BY 1 START WITH 1 CACHE 20 NOORDER NOCYCLE NOKEEP NOSCALE,
    name VARCHAR2(100) COLLATE USING_NLS_COMP,
    created_date DATE
) DEFAULT COLLATION USING_NLS_COMP;

The issue was simple string concatenation creating invalid paths like AUTOINCREMENT_/tmp/output.sql instead of /tmp/AUTOINCREMENT_output.sql.

Fixed it by fileparse() to split the path properly and File::Spec->catfile() to put it back together correctly.

This affects these files:

• TBSP_INDEXES_*
• PARTITION_INDEXES_*
• AUTOINCREMENT_*
• LOGICAL_*
• INDEXES_*
• FTS_INDEXES_*

Should be backward compatible since it's just fixing the path construction, not changing what gets generated. Tested with different output directory scenarios and it works as expected now.
