[8u]RFR: 8263061: copy wrong unpack200.diz to bin directory on linux after 8252395

[kalinshi(施慧)]

Hi,

Please help review this fix.
After 8252395, unpack200 executable is wrongly copied to bin directory as unpack200.diz when configure with debuginfo.

Makefile sets same prerequisite for unpack200 executable and debuginfo file. install-file function always copies first prerequisite, which is executable.
Fix is use debuginfo file as first prerequisite and copy it.
