sim: Move getopt checking inside SIM_AC_PLATFORM
This commit moves getopt declaration checker originally in sim/
configure.ac; added in commit 340aa4f6872c ("sim: Check known getopt
definition existence") to sim/m4/sim_ac_platform.m4 (inside the
SIM_AC_PLATFORM macro).
It also regenerates configuration files using the maintainer mode.
