  [HIP] Fix unbundling archive

HIP is able to unbundle archive of bundled bitcode.
However currently there are two bugs:

1. archives passed by -l: are not unbundled.
2. archives passed as input files are not unbundled

The actual file name of an archive passed by -l: should
not be prefixed with lib and appended with '.a',
but the file path is prefixed with paths in '-L' options.

The actual file name of an archive passed as an input file
stays the same, not affected by the '-L' options.
