[klibc] dash: [PARSER] Removed unnecessary pungetc on EOF from parser

[ dash commit a31c812b02d7fc331f8a0c5aedbbf12b4025c1db ]

Doing a pungetc on an EOF is a noop and is only useful when we
don't know what character we're putting back.  This patch removes
an unnecessary pungetc when we know it's EOF.
