[LTP] [PATCH v2] isofs.sh:Run test on genisoimage, xorriso &mksisofs if not symlinks

[Subramanya Swamy]

    1)mkisofs, genisoimage and xorriso tools are present as separate
    tools in some distros while in others they are symlinks to one
    another. Tests are skipped on symlinks.

    2)mkisofs supports only -hfs option
      genisoimage supports both -hfs & -hfsplus options
      xorrisofs supports only -hfsplus option

=> this change actually fix xorrisofs on CentOS, see below.

First, we are just to release LTP version today and we would like to avoid last
minute changes. Looking to the original version, the attempt was to fix
xorrisofs on CentOS which is a symlink to mkisofs and because it does not
supports -hfs test IMHO fails. So I would be for merging this (with a diff, thus
I repost as v3), but depends on Cyril.

IMHO this is not needed, we check for command in the test itself.

This is clearly broken formatting (test uses tabs, but you add spaces, we care
about it as it would break readability).

I prefer local to be at the beginning of the function.

{ } brackets are not needed, but quotes are.
Missing quotes actually causes -hfs -D being split (run separately)

Kind regards,
