post-install system ignores some values from plan9.ini

[GoogleCodeExporter]

Some values are not making it from `plan9.ini` into `#ec` and `#e`.

The following is output from a freshly installed terminal:

{{{
term% cat /n/9fat/plan9.ini
bootfile=9pcf
bootargs=local!/dev/sdC0/fscache
sysname=cirno
mouseport=ps2intellimouse

*nomp=

term% ls '#ec'
'#ec/*nomp'
'#ec/bootfile'

}}}

This is the relevant portion `/sys/src/9/boot/bootrc`, as it existed when the 
system was built:

{{{
# convert plan9.ini variables
set init
set user
set nvram
set rootdir
set bootargs
set nobootprompt
set sysname
set debugfactotum
set fs
set fsaddr
set auth
set authaddr
}}}

Note: vgasize from plan9.ini is making it into both #ec and #e.

When booting, the contents of plan9.ini are printed correctly on the screen. At 
the bootargs prompt, drop into a shell with !rc. The $sysname variable is 
empty, #ec/sysname does not exist, and #e/sysname exists but is empty.

When 'set sysname' is removed from bootrc and the kernel is rebuilt, echoing 
$sysname at the !rc prompt produces non-ascii garbage characters.
