erlexec: Make ERL_<version>_FLAGS behave like ERL_AFLAGS
The contents of the ERL_<version>_FLAGS undocumented environment variable would be added at the end of the command line passed to the BEAM emualator (similar to ERL_ZFLAGS), making it impossible to override (for example) "-smp" with "-smp disable" on the command line. To allow overriding, put the contents of ERL_<version>_FLAGS at the beginning of the command line (similar to ERL_AFLAGS). Since the ERL_<version>_FLAGS variable is undocumented and unsupported, it is OK to change its behaviour in a minor release.
