[Automake-NG] [FYI] tests: amopts-variable-expansion.sh: fix post-merge spurious failure

[Stefano Lattarini]

* t/amopts-variable-expansion.sh:: Adjust to reflect the fact that subdir
sources no longer require AM_PROG_CC_C_O in 'configure.ac'.  Instead, use
the fact that 'AM_PROG_AR' is required to be in 'configure.ac' when a
library is to be built and warnings in the 'extra-portability' category
are enabled.
