fixup! [4.0] Use strip (instead of eu-strip) to support --strip-debug of *.so at build time

The command strip has been in use building for chromium-efl like below.

$ strip --remove-section=.comment -o /PATH/TO/libchromium-ewk.so.debug /PATH/TO/libchromium-ewk.so

Also, it has been expected that
the argument libchromium-ewk.so.debug will have section .debug_*
and another argument libchromium-ewk.so will be stripped.

Btw, the libchromium-ewk.so.debug doesn't have the section .debug_*
but the libchromium-ewk.so still has the section.

The argument files need to be switched each other.
With this CL, the libchromium-ewk.so.debug properly has
the section .debug_* like below and libchromium-ewk.so is stripped.
