ITPParser doesn't like some relative paths

[richardjgowers]

Actual behavior

Relative paths (when going "upwards"/../) in the ITPParser seem to fail.

I think that all is needed is for find_path to have an abspath call early on, as absolute paths seem to work fine.

Code to reproduce the behavior

cp file.itp ./
mkdir something
cd something

import MDAnalysis as mda
from MDAnalysis.tests.datafiles import PSF, DCD,  GRO, PDB, TPR, XTC, TRR,  PRMncdf, NCDF

u = mda.Universe('../file.itp', format='ITP')

....

Current version of MDAnalysis

• Which version are you using? (run python -c "import MDAnalysis as mda; print(mda.__version__)")
• Which version of Python (python -V)?
• Which operating system?

Hi @richardjgowers , I am student just learning how to develop code. In this situation, I found find_path in the ITPParser file, but I am unable to locate where the abspath function is at? Sorry, this might seem like a trivial question.
