util: fix parseArgs skipping first positional arg with --eval= and --…

[azadgupta1]

Fix: handle --eval= and --print= correctly in getMainArgs()

Fixes #60808

parseArgs() was skipping the first positional argument when Node was started
with --eval= or --print=. The logic only checked for --eval / --print
and missed the --eval=... / --print=... forms.

This patch adds startsWith('--eval=') and startsWith('--print=') checks so
getMainArgs() returns the correct slice of process.argv.

After this fix, positional arguments are preserved correctly for all eval/print forms.
