Subject: Call hwmatch only on the grub-pc platform
Call hwmatch only on i386/pc as it is only available there.
This avoids "error: can't find command `hwmatch'." on e.g., x86_64/efi.
The equivalent behavior is linux_gfx_mode=keep because grub is special:
the `if hwmatch` clause is true on that error and `$match = 0` is true
too, as it is undefined (confirmed in grub shell.) A quick fix for now.
Before and After:
grub> hwmatch
error: can't find command `hwmatch'.
grub> echo $grub_platform
efi
grub> echo $linux_gfx_mode
keep
