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.
