mksh: bump to R55 and use PKG_HASH

Upgrade the package to R55. Patches refreshed.

Added `-DMKSHRC_PATH=\"/etc/mkshrc\"` to `CPPFLAGS` to set the default
startup file during both login and nonlogin sessions, so that there is
no need to source `/etc/mkshrc` file manually.

In addition to the package upgrade, use PKG_HASH instead of
PKG_MD5SUM.

+Subject: [PATCH] Refresh 100-dot_mkshrc for mksh-R55
+
+Additional changes of the patch as of mksh-R55
+* Use content of `/proc/sys/kernel/hostname` to set `$HOSTNAME`, since
+  `hostname` applet isn't compiled into `busybox`.
+* Use `/bin/vi` as fallback `$EDITOR`.
+* Use `/etc/mkshrc` as default startup file, so there is no need to
+  manually source it during interactive session.
