MIPS: Rename "mips" arch to "mipsel" in the GYP build.

In the traditional MIPS naming scheme, "mips" is used for
big-endian mips and "mipsel" is used for little-endian mips.
In V8 the "mips" build is little-endian, so the "mips" target is
renamed to "mipsel" to be compliant with the traditional MIPS
naming scheme.

This change is also required for supporting the Chromium project on MIPS.
